Question: Write a short note on the fertility of soil. Answer: The capacity of the soil to sustain the plant life with required nutrients is called the fertility of the soil. The fertility of soil reduces mainly due to soil erosion. When..

Constant use of the soil leads to the loss of its important nutrients particularly nitrogen, phosphorus and potassium and thus the soil loses its fertility. For the healthy growth of the plant these deficiencies in the soil have to be replenished with the use of certai..

These are land plants which grow in moist habitats and need well aerated soils. They prefer soil and air with moderate humidity. They avoid soils with standing water and soils containing great abundance of salt..

The chemical effluents released by industries have altered the composition of soil in deeper layers and have caused imbalances in the nature of soil..

It has been noted that in the dihybrid genetic crosses, a recombination frequency of less than 50% indicates linkage of the two genes involved. Morgan and Sturtevant found that the recombination frequency varies for different mutant gene pairs. The difference in the recombination frequenc..

The growing of different kinds of crops on a piece of land in a preplanned succession is known as crop rotation. In the rotation of crops, leguminous crops like pulses, beans, peas, groundnut and Bengal gram are sown in-between the seasons of cereal crops like wheat, maize and pearl millet. The leg..

Question: List out the different types of soil. Answer: Soil is classified on the basis of its nature and composition into 6 main types. Namely: Alluvial soil which is rich in loam and clay Black soil which is predominantly clay Red so..

Vermicompost is a type of soil made by earthworms and microorganisms as they eat through organic wastes. The soil thus produced is mainly worm excreta and finely ground soil. Organic wastes can be collected and fed on by worms so that the end product is the broken dow..

It has been noted that in the dihybrid genetic crosses, a recombination frequency of less than 50% indicates linkage of the two genes involved. Morgan and Sturtevant found that the recombination frequency varies for different mutant gene pairs. The difference in the recombination fr..

In the year 1902, Boveri and Sutton proposed the idea of chromosome theory of inheritance which was subsequently confirmed by Morgan in the year 1933. According to this theory, the Mendelian factors which are now called as genes, are located on the chromosomes and it is the chromoso..
