METHOD FOR DETERMINING RESISTANCE OF PLANTS TO SOIL DRYNESS Russian patent published in 1997 - IPC

Abstract RU 2080057 C1

FIELD: agricultural technology. SUBSTANCE: resistance of plants to soil dryness is determined by growing test samples in dry soil testing site. Used for sowing are two types of dry soil testing sites. For evaluating indications of drought-durability, use is made of soil substrate in testing site 0.5 m deep which is completely isolated from soil moisture, and for determining of drought-evading, soil substrate in testing site is isolated from soil moisture only in vertical plane. Yield produced in testing sites is compared with yield of standard plants. EFFECT: high efficiency. 1 dwg, 2 tbl
