SU683700A1 - Method of reclaming sandy soil - Google Patents

Description

that of clay, slurry, low-grade phosphorites, surface active agents (surfactants), for example, dimethylsilanoyl or silicone and clinoptilolite in proportion, ee. %: clay 40-50, liquid manure 18-2O, | low-grade phosphorite 12-15, surfactant, clinoptilolite 5-8, water - the rest. The use of these components as a layer allows one to lock nutrients and ensure their gradual return for plant nutrition, to create an optimal water-air and nutritional regime for plant growth and development, and to prevent environmental pollution. Laying; puffs 2-4 cm thick at a depth of the lower arable layer of 1–12 cm ensure effective work for 23 years. The method is carried out as follows. Before applying the interlayer, a homogeneous pasty mass is prepared in any container (91-95% 04% moisture), by thorough mixing, for example, on concrete mixers of components (wt.%): Clay 4O-50, liquid manure 18-20, low-grade phosphate 12 -15, surfactant 0.10-0.15, clinoptilolite 5-8 and water - the rest. With the help of the AIM-36 machine, the paste is brought into the field and introduced into the subsurface layer with combined units for liquid and semi-liquid manure. Field experiments to study the effectiveness of anti-filtration screens for sandy soil Poles were carried out on the collective farm. Ilyich Mostkinskogo district of Sumy region. At a depth of 4O cm, 10-12 cm below the arable layer, a combined aggregate for the subsoil application of liquid and semi-liquid manure laid a layer at the rate of 100 t / ha. The characteristic of various variants of the layer is presented in the face.

 Tf rJ-TftJTj 96 Notes: When executing the interlayer (clay 40-50%, the rest is water), the water consumption per filter is reduced to 0.5-1.0 cm / day. Nutrient losses decreased, kg of active substances / ha: C to 0.11-0.18; PjOg to 0.19-0.31; KjO to 0.46-0.60. 2. When making the interlayer - clay 51%, the rest is water - water filtration decreases to 0.05-0.1 cm / day, which negatively affects the growth and development of plants. With low filtration, the water-air regime of the soil and root system is disturbed. 3. When making a layer of 45% clay, slurry and water else, filtering does not significantly change (0.5-1.0 cm / day), but the loss of nutrients is reduced due to adsorption; N TO O; P About 0.12-0.18; 0.28-0.31. 4. The content of manure more than 20% does not cause changes, therefore, to increase its amount is uneconomical. 5. The addition of 0.10-0.15% methylsilanol or silicone gives the necessary consistency to the interlayer and adsorption capacity. 6. Increasing the content of methylsilanol (silicone) by more than 0.15-0.16% causes the layer to be structured and, consequently, an increase in filtration of 1 to 1.5-1.9 cm / day. The loss of nutrient substances at the same time increase: N to 0.11-0.16; PgOj 0.07-0.27; KjO 0.2 0.31. When the content of silicone is 0.16% or more, the adsorption capacity of the organic-colloidal part of the interlayer is reduced and the binding of its active groups occurs. 7. Supplements of clinoptilolite up to 5-8% contribute to the absorption capacity of the interlayer, which prevents potassium extinction to 0.08-0.14. 8. The addition of clinoptilolite more than 8% is not economically viable. 9. The addition of low-grade phosphorite up to 12-15% is optimal, contributes to plant growth. Y. Low grade phosphorus contains a lot of ballast, which negatively affects the adsorption and absorption capacity of the interlayer. Therefore, the addition of low-grade phosphate more than 15% leads to an increase in filtration and a decrease in the absorption capacity of the interlayer. The loss of nutrients at this 0010 increase: - to 0.08-0.15; K-0.20-0.28. 11. The slider thickness of 2-4 cm is optimal, it prevents the leaching of nutrients. The loss of N is reduced to O; , 02- 0.08-0.13 with x loss of water to filter 0.51, 0 cm / day. 12. An interlayer of layers (shoy 1 cm is inefficient, because there is a great loss in filtration, and, consequently, loss of nutrients. A layer 5 cm thick and more economically unprofitable, since the material consumption is large, and the effect is the same as with 4 cm interlayer. Using the proposed method of preventing the loss of water and nutrients when growing plants on sandy soils provides the following advantages in comparison with existing methods: a) nutrient losses almost completely stop runtovye water, which allows to make higher doses of fertilizers in sandy soil conditions Poles and prevent contamination of ground vodg b) promotes mobilization catalytic phosphorus from low grade phosphate rock plant root system, which increases their utilization ratio; c) promotes the slow decomposition of organic matter and the gradual release of nutrients and mineral components of the mixture by plants: d) lengthens the life of fertilizers, which to a certain extent reduces their consumption and increases efficiency: e) significantly reduces unproductive water losses and creates optimal water air and food regime for plant growth.
