Soil conservation is
(a) conversion of sterile soil into fertile one
(b) aeration of soil
(c) erosion of soil
(d) protection against loss.
The correct answer is option D , protection against loss.
Soil conservation is defined as prevention of soil loss.
So from given options option D is correct one.
The remaining options we can ignore
Soil conservation is (a) conversion of sterile soil into fertile one (b) aeration of soil (c)...
Timoracam X (A genome) Ticarsi (B genome) sterile hybrid 1. turgidum (Emmer wheat) fertile hybrid 4. During the evolution of wheat, two wild diploid species were crossed to form Emmer wheat (Triticum turgidum). One diploid (2n = 14) T. monococcum had the A set of chromosomes and the other diploid (2n = 14) T. searsii had the B set. The initial cross produced a sterile hybrid, from which a fully fertile hybrid eventually arose, as shown below: Imam X genome)...
Two species interbreed occasionally and produce vigorous, fertile hybrids. When the hybrids breed with each other or with either parent species, however, the offspring are feeble or sterile. These species are affected by a) gametic isolation. b) reduced hybrid fertility. c) reduced hybrid viability. d) hybrid breakdown.
