The human population on the planet is estimated to reach 9 billion by 2050; this requires significant increase of food production to meet the demands. Intensified farming systems have been identified as a viable means to increase grain production. Crop production inputs include carbon investment in the form of energy, for the manufacture and use of farm machinery, synthetic fertilizers, crop protection chemicals such as herbicides, insecticides and fungicides, groundwater irrigation and the direct use of fuel in farm operations.

A study was conducted in an ongoing field experiment started during Rabi 1988-89 in calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The experimental design was split-plot with four fertilizer levels (0, 50, 100 & 150% NPK) in main plots and four levels of manures (no manures, compost @10 t ha-1 , crop residues and compost @10 t ha-1 plus crop residues) in sub-plots.

Two consecutive field experiments after rice crop were conducted during 2011-12 and 2012-13 in the Crop Research Centre, of Sardar Vallabhbhai Patel University of Agriculture and Technology, Uttar Pradesh. Ten different treatments were implied to evaluate the residual effect of vermicompost and applied inorganic fertilizers on wheat crop. Significantly taller plants than T2 during both the years were measured in those treatments where 4 ton vermicompost was applied in rice.

Rice-wheat (Oryza sativa L.-Triticum aestivum L.) rotation is the major production system in Asia, covering about 18 million ha. Continuous and conventional RWC system practice has witnessed a significant slowdown in the yield growth rate. The sustainability of this important cropping system is at risk due to second-generation problems (low fertility status, multiple nutrient deficiencies, and imbalanced use of fertilizers, ground water depletion at faster rate, soil salinization, and inadequate system diversity).

Field experiments were conducted during 2010-12 at Regional Research Station, Virudhachalam to find out the residual effect of fly ash, farm yard manure and fertilizers applied to groundnut on growth parameters, nutrient uptake, yield of sesame and post-harvest soil available nutrients. The Neyveli Lignite Corporation fly ash contained higher amount of Ca, Mg, S and Si, moderate amount of P, K and B. Application of fly ash @ 40 t/ha significantly increased growth parameters, yield attributes, seed yield and harvest index of sesame.

The excess usage of synthetic fertilizers with minimum application of organic inputs results into nutrient deficiencies, deterioration of soil and also causes environment pollution. It also affects the sustainability of agricultural production. Sustainable agricultural production includes the management of soil organic carbon, use of organic manure such as animal manure, green manure, crop residues, and sewage sludge. Since only organic manure cannot fulfill the nutrient demands of agriculture crops, hence integration of fertilizers and organic sources is the need of the hour.

India is facing various challenges in agriculture sector for sustaining soil fertility and food grains production, besides environmental degradation and food security of the country in the event of ever increasing demands of food grains production with limited cultivable land. Cultivable land and maintaining its soil fertility are one of the major tasks which supports about 17.6% of its population and leads to fact that, our natural resources are under considerable strain. Food grains are a major source of energy and are thus are vital for food and nutritional security.

Soils in India are declining in fertility status due to higher usage of synthetic fertilizers and mono-cropping practices. To maintain the sustainability of soil and better crop production, it is essential to retain physical, chemical and biological properties of the soil through optimum level of organic matter. This article deals on the literature related to biochar, its production and characterization and its effect on soil application. The biochar application to the soil is a novel technique to improve soil fertility and thereby the soil productivity.

Distributions of different zinc (Zn) forms in seven blocks of rice-wheat growing soils of Jammu region were studied. Understanding the Zn distribution in soil is important for efficient and effective management of the fertilizers recourses and to achieve a higher productivity rate. Sequential extraction scheme was used to fractionate Zn into Water Soluble + Exchangeable (WSEX), Organic Complexed (OCx), Amorphous sesquioxide (AMOX), Crystalline Sesquioxide (CRYoX) and Residual zinc (Res Zn).
