Soils of long term fertilizer experiment
-
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.

A long term field experiment was conducted since kharif 2015 for evaluating the effect of inorganic and organic sources of nutrients on soil physical properties and productivity on direct seeded rice ( Oryza satia L.) – MTU1010 under rainfed midland situation at Bastar plateau zone at S. G. College of Agriculture and Research Station, Jagdalpur, Chhattisgarh. Random block design was used with twelve treatments and four replications to carry out experiment. The full recommended dose of fertilizer for rice crop was 100kg ha-1 Nitrogen, 60 kg ha-1 phosphorus and 40 kg ha-1.

The field experiment was conducted the year 2014-2015 on the old long-term fertilizer experiment started since 1983 to assess characterization of humus in soil and it’s relation with physical and physic-chemical properties of soil under the long – term effect of integrated nutrient management in sorghum wheat cropping system. The study showed that there was fraction of humus tended to decrease with depth and use of organics like subabul and FYM in conjunction with NPK fertilizers exerted a remarkable impact on the distribution and built up of humus fractions in soil.

Studying the dynamics of soil organic carbon (SOC) is important for understanding the carbon stabilization into different pools. Thus, a 25-year old experiment was used to assess the impact of double rice cropping system with addition of organics and grades of fertilization on labile carbon pools and crop yield sustainability in an Inceptisol in southern India. The total water stable aggregates (WSA) in the experimental soils ranged from 70.4 to 94.9% under different treatments.

Integrated nutrient management system (INMS) gained importance not only in increased yield of crops but also in maintaining the soil health and fertility. Keeping these in views a field experiment was conducted at Mountain research centre for field crops Khudwani (SKUAST-Kashmir) during 2013 (in progress since march 2008) to study the Effect of INM on soil carbon pools and soil quality in rice-brown sarson cropping system with different treatment combinations.

The changes in enzyme activities, microbial diversity and nutrients availability in soil under long term fertilization (30 years) with inorganic fertilizers alone or in combination with organics/amendments were investigated in the present study. The experiment consisted of eleven treatments with four replications with the finger millet-maize cropping sequence. Significantly higher biomass C (276.53µg/g) and biomass N (27.20 µg/g) contents were recorded with 100 % NPK+FYM+lime and 100 % NPK+FYM application respectively.

A long-term field experiment was conducted to design and implement alternative production systems with increased resource use efficiency, productivity and to determine the effect of tillage systems and mineral fertilizers on soil organic carbon patterns. This experiment intended to evaluate the effects of these management strategies on soil structural formation and structural stabilization of a sandy loam soil. The shift from puddled - transplanted rice on the flat land to raised bed systems affects the productivity and resource use efficiency of the rice-wheat system.

Variability in climate regimes of rainfall and temperature is a source of biotic and abiotic stresses in agricultural systems worldwide. This study examines seasonal and annual rainfall and temperature variability in rice, wheat and jute crop productivity for five decades (1972–2012) under long-term fertilizer experiment in alluvial soils of eastern India. The climatic variations and impacts were captured using a standardized precipitation index (SPI), diurnal temperature range (DTR) and crop productivity index (CPI).
