Soil organic carbon has been ignored since long because it was treated as a dead biomass but after the awareness related to climate change its importance has been recognized. A study was conducted to eliminate the SOC pool under different land uses in Rudrapryag district of Uttarakhand.

Barren soil undergoes several changes in its physical and chemical properties when brought under tree cover. Trees influence the soil by providing shade and litter at the surface and through their roots in the sub-surface layers.

Biomass estimation and productivity studies were conducted in 3, 6 and 9 years old plantations of Dalbergia sissoo in sodic lands of Sultanpur District in Eastern Uttar Pradesh, India. A set of regression equations for biomass production per unit area was also developed to be applied on regional basis.

The changes undergone by physico-chemical properties of soil, profile morphology and the productivity index, as a result of bringing the barren land under Poplar plantation, were evaluated in Yamuna Nagar District of Haryana, where large chunks of land have been raised as block plantation with Poplar. The soils supporting Poplar plantations were enriched with organic carbon and nutrients.

A field experiment was conducted in Allahabad District of Uttar Pradesh to test the possibility of utilizing fly ash, in afforestation of sodic soil with Albizia procera, as a substitute of fertilizers and amendments. Fly ash proved to be a good substitute of rice husk, was superior. Similarly the treatments where fertilizer was replaced with fly ash have also shown better performance of plant.

Kullu is a major growing district of Himachal Pradesh. The study was undertaken with the specific objective to examine the cost of cultivation of garlic in the valley in terms of various farm management cost concepts.
