METHOD FOR DETERMINING SOIL NUTRITION AREA OF AGRICULTURAL CROPS

摘要

FIELD: agriculture.;SUBSTANCE: method involves determining the area occupied by plants sown by the hexagonal pattern. The effective nutrition radius of crop plants is preliminary determined. Thereinafter the volume of the soil nutrition area is determined, which is the product of the area occupied by the plant and the penetration depth of the roots. Wherein the volume is determined by the volume of a regular prism with the base in the form of a regular hexagon, and the area occupied by the plant is determined by the area of the regular hexagon obtained by joining the middle perpendiculars of distances to the nearest six plants and forming the base of a regular hexahedral prism. The penetration depth of the roots is determined by a segment drawn perpendicularly from any point of the regular hexahedron down to the depth of 0.35 m and being the hexagonal prism height.;EFFECT: method allows to determine the soil nutrition area of agricultural crops.;2 dwg
