A second maximum in evaporation rate is reached when the aggregate size exceeds 50mm, which is often the case in soils with high clay content. These aggregates are not small enough to permit capillary transport of water, but not large enough to create turbulent air flows. Soil fertility management 2.10a, b & c). Terracing of slopy lands helps in conserving soil and moisture and prevents soil erosion. Actually with the addition of goat excreta, there is improvement in the physical properties like soil structure, water holding capacity and porosity. So the addition of night soil/human excreta along with soil from cultivated field improves the soil fertility. This type of bunding and terracing is continuing from centuries and terraces are still intact. Farm yard manure is transported to the fields in Kilta (bamboo container) by people's participation (Fig. The crops are chosen as per their nutrition e.g. risers, curtain drains) –Land forming on soils with poor internal drainage • Soil water –Drain tile: Soil must be saturated for water to enter tile The same method is adopted to irrigate the following compartment. Other practice is to harvest crops as close to the grounds as possible. It is also stored in dugout structures. Fig. The burning of crops is due to the toxic effects of high levels of nitrogen, phosphorus and potassium in goat and sheep manures. Ash dust is also useful in enhancing the maturity of bulb crops which normally takes 6-7 months for obtaining economic yield. With aggregates of this size in a seedbed, a lid is put on and evaporation of water is minimised. years now. In our traditional agriculture there is a common practice that during the preparation of a field the slope of a field, is kept inside which is provided with a channel to take excess water from that field to a safer place, from where it is disposed to stream or nalla through grassed water ways. sixth compartment is irrigated first followed by fifth and so on. Crops such as maize, capsicum, tomato which are grown during this season are very sensitive to water logging. The practice of collecting soil from cultivated land and fields helps in easy ploughing during summer cropping. As they are heavier, they fall on soil surface and make the layer moist and wet. water in fields, Use of kuhl water Väderstad Tempo is a new generation high-speed planter, delivering an unmatched precision at double the speed of traditional planters. Construction of Fig. It is easy to plough fields manured with goat excreta. The main objectives of soil and water conservation are to obtain the maximum sustained level of production from a given area of land by preventing soil degradation and environmental pollution. In most Himalayan cold deserts water is brought in channels from glacial melts for irrigating the fields. In cold deserts, some villages get water for irrigating their lands from some perennial torrents. 2.14a Village water pond where Pang (spang) grass is used. Stone wall fencing is also constructed for individual land holdings. Barley and wheat stumps (in Zanskar) are pulled out by hand along with the complete root system. Within the premises of the house it is mandatory to have fruit plants such as citrus, mango, anar which provide seasonal fruits rich in vitamin C., carbohydrates etc. Necessary cookies help make a website usable by enabling basic functions like page navigation and certain functionality. December and January (Fig. Fibrous rooted shrubs and grasses planted as hedges along the contour of the land slow the runoff, weaken the erosive power of water and cause it to deposit its load of valuable soil behind the hedgerows. These flocks when taken for grazing are tied with small bags which cover their anal parts so that the excreta falls right into the bag. In Spiti valley, the farmers have developed the irrigation water distribution system on the basis of their land holdings, in which every field is irrigated timely. Rapid is a seed drill that carries out seedbed preparation, levelling, drilling and reconsolidation in one pass. Fig. The night soil/human excreta possess immense manurial potentiality as it contains the major plant nutrients like nitrogen, phosphorus and potassium. Sources of irrigation water 2.17g Stone terraces along the slope, Fig. The website's functionality is, to some extent, dependent on cookies. The roots of grasses help in binding and keeping the boulders intact at a place. Soil sampling and testing are essential to determine soil properties and fertility levels to make good management decisions about fertilizer, manure, and lime application rates. Soil is a complex matrix of solid materials and void spaces which perform numerous functions essential for life “as we know it” on planet Earth. Wheat is often pulled out while standing, but kneeling or squatting is practiced for barley. With the onset of summer months it is spread in the open field. In addition to this, human excreta and household waste also contains good amounts of nitrogen, phosphorus and potassium. In this method of vegetation, live check of bambo pieces and loose boulders are used for controlling gully erosion (Fig. Fig. There is traditional practice to keep surface maximum covered with grasses, shrubs etc., grazing is done in rotation and is allowed only during certain times. 2.4 Bamboo pipe - commonly used for irrigation water flow on depressions/small nala from one field/terrace to another. 2.22 & 2.23). Alternative soil-management methods, choices of crop species, and harvesting techniques can contribute to soil fertility, pest management, and amount of water available to crops in rotations. Secondly area under crops remains the same as that of previous crop i.e. The water channels are built and managed by the villagers with no government assistance. Ploughs are broadened in Ladakh by attaching flat wooden pieces to both sides of the iron blade. One cannot control slope, texture, climate and other critical soil factors but can surely control tillage, crop rotations, soil amendments and other management choices. The management of water in a particular field is regulated by apportioning into different compartments because of the season. Use of Pang (Spang) Grass for Controlling Seepage and Side Losses in Water Tanks and Irrigation Kuhls. From old times, land in the hills has been put under cultivation on scientific lines as cultivation is done up to 25-100 degree slope, where there are many chances of landslips, sheet and gully erosion. Soil is the most important component, as any effect on it, directly influences and changes other components. The pitcher once filled, supply sufficient moisture for atleast two weeks and then again it is filled with water. 2.12c Village rain water pond for irrigation and livestock. 2.9) and in Spiti valley ladies bring water to their fields using Urma which is made from animals horn. The height of riser is again decided by the degree of slope. Another method is the collection of spring water in small reservoirs scattered at intervals on the high uplands and then drawing water from these ponds when required (Fig. Good bottom soil and water quality are an essential ingredient for any successful aquaculture practices. Sometimes ashes are also broadcasted in the fields. This is necessary for maintaining the high speed of the water mills wheel (Fig. The manure is directly mixed with the soil while ploughing. In the West Himalayan cold deserts, all the irrigation channels (Kuhls) cannot be run satisfactorily due to non-availability of sufficient water from Nallas/Khads. bamboo pipes are commonly used as irrigation channels on depressions/small nala (Fig. 2.1). 2.28). This practice helps not only in the rational land use but also checks soil erosion in otherwise sandy and loose strata. During rainy season the rains are torrential, which causes splash erosion resulting in the sorting of particles and the formation of false compact layer on the surface. Long wooden channel placed at steep gradient is used for maintaining the high speed of the water flow. Retention" of roots in soil (in single cropping) contributes towards humus availability which improves the soil structure, porosity and water holding capacity of the soil. The spreading of this mixture as an organic manure, increases the size of potatoes on account of optimum supply of nutrients in otherwise nutrient deficient soils. 2.7a/b). The practice of keeping small heaps of manure in open field with soil coverage in high altitude zones helps in better decomposition due to the maintenance of better temperature conditions. through mulching The pitcher is filled with water during summer months (April-June) and stone/slate lid is placed on the top. for running water mills Fig. Goat manure when added to millet fields improves production. The manure is broadcasted in the entire field, which is followed by ploughing for thorough mixing. In the lower areas of Himachal Pradesh, Mango plants are mostly damaged by frost injury during winter months i.e. The choice of crop and rotation, completely depends on crops which require less volume of water. Fig. Coverage of organic manure (FYM) with soil in open fields throughout winter helps in regulating (heap) temperature necessary for proper decomposition of FYM. These cookies are technically necessary for you to enjoy the websites and cannot be opted-out from. 2.15). The collection of dropping of sheep and goats by tieing bags is indicative of indigenous wisdom to meet out the shortage of manure. It has been observed that dusting of material in the fields enhance early maturity and high yield of vegetable crops. 2.23 Green pine needles spread for bedding in cattle yard. The moist upper layer of soil which gets frozen in winter also serves as a protection against wind erosion. Fig. By ploughing, moisture is mixed with soil particles in the plough layer i.e. 2.17h Bench terrace fortified with vegetative measures. 2.18 Loose boulders spurs - reduce cutting effect of stream flow in 'choes', Use of loose boulders diversion dam with spillway in centre for reducing soil erosion. However, in some parts the wooden channels are also used which are put like a bridge over the path. Moisture conservation 2.4 Available water content. The roots are made to stay in soil for humus production. and water management techniques, Construction of Repair & Maintenance of existing drains. 2.8). Diverting ‘clean’ water flows away from work sites. Thirdly the soil added in lower fields from the bunds of upper field is rich in nutrients and it improves the soil fertility. The reason for the early maturity of cucurbits and vegetable crops is due to the fact that ash dust contains sufficient quantity of phosphorus in available form to the plants. The whole community is divided on the basis of number of farm families and one family gets one full water day to irrigate their fields turnwise. Soil management The ears of the lower row are covered and protected from birds by the roots of the upper stacks. On such silt soils it is important to interrupt capillary transport so that water is not lost. 2mm, water evaporation is minimised. The pneumatic seed drill Spirit carries out levelling, seedbed preparation, reconsolidation, seeding and pressing in one pass.
