Long term fertilization on soil properties
-
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.

The status of nutrients-their depletion and build up in soil and crop productivity after twenty two years (1991-2012) of cotton mono-cropping were studied under continuous use of various inorganic fertilizers and organic manure in a Vertisol. Results showed that application of 100% RD of NPK (90:45:45 kg ha-1 ) +FYM @ 10 t ha-1 recorded highest seed cotton yield of 2181 kg ha-1 which was on par with 150% RD of NPK treated plot.

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.

Groundnut is the mostly grown commercial oilseed for millions of small scale farmers in the semi-arid topics and under rainfed conditions in Andhra Pradesh. The productivity of groundnut grown under rainfed situation is declining from the actual production of 1.23 m t to the lowest yield of 0.8t ha-1 in India, under the crop area coverage of 1.38 m ha.

An investigation was carried out at Norman E. Borlaug Crop Research Centre of G. B. Pant Univ. Agric. & Tech. Pantnagar, U. S. Nagar, Uttarakhand, India in order to study the influence of long-term applications of fertilizers and manures on different soil physical properties after forty two cycles in silty clay loam textured Typic Haplustept under ricewheat cropping sequence during 2012-13. The field was laid out in a randomized block design comprising of ten treatments.

The present investigation was carried out to study the effects of long-term application of inorganic fertilizers and organic amendments on soil organic matter level, soil biological properties and plant nutrient reserves. The continuous application of organic amendments for the last ten years under cotton-wheat cropping system at CCS H.A.U, Hisar had beneficial effects on soil chemical, arginine ammonification and nitrification activity as compared to application of chemical fertilizers.

The long-term application of excessive chemical fertilizers has resulted in the degeneration of soil quality parameters such as soil microbial biomass and nutrient content, which in turn affects crop health, productivity, and soil sustainable productivity. Organic manuring and Integrated nutrient management system (INMS) gained importance in maintaining the soil health and fertility.

The rice-wheat cropping system, which is considered as the backbone of food selfsufficiency, is facing a sustainability problem due to practices of modern production system with indiscriminate use of chemical fertilizers and pesticides. So, effects of long term use of mineral fertilizers and farmyard manure (FYM) under rice (Oryza sativa)– wheat (Triticum aestivum) cropping system in a Mollisol was investigated. Rice and wheat yields were highest (51.47 and 48.60 q ha-1 , respectively) with 100% NPK + 15 t FYM ha−1 and lowest in control (13.72 and 11.85 q ha-1 , respectively).

In the Canadian Prairies, there is particular concern about the depletion of soil phosphorous from organic grain production [7], and the long-term impacts of tillage practices employed by organic producers [8]. Grain yields under organic management are, on average, lower than under conventional management, and it has been suggested that the yield deficit is more severe on the Canadian Prairies than some other regions [9].
