“…The lowest concentration of water soluble K in present investigation might be attributed to the fact that the K in the soil solution is more easily utilized by the crop [ 17 ]. Sawarkar et al [ 18 ] discussed the contributions of various potassium (K) fractions in soil, ranking them as follows: lattice-K > non-exchangeable-K > exchangeable-K > water-soluble-K. A similar trend in the abundance of K fractions in soils was also observed by Soremi et al [ 19 ]. In a recent study, Jadhao et al [ 20 ] reported the sequential dominance of K fractions in Vertisols of Akola as follows: lattice K > non-exchangeable K > exchangeable K > available K > water-soluble K. Earlier, Prakash and Singh [ 21 ] found the water-soluble K fraction to range from 8 to 50 mg kg -1 with a mean value of 18.25 for surface soil and 16.45 mg kg -1 for sub-surface soil.…”

A field experiment was conducted at the Research Farm of the ICAR-Indian Institute of Soil Science, Bhopal (India) to study influence of different integrated nutrient management (INM) modules on soil potassium (K) fractions. The experiment comprised with twelve treatments laid out in randomized block design (RBD) with three replications under maize-chickpea cropping sequence. The treatments included general recommended dose (GRD), soil test crop response (STCR) dose; combinations of inorganic and organic inputs and only organic modules. The soil samples were collected at crop harvest and analyzed for various K fractions viz., water soluble-K, available-K, exchangeable-K, HNO3-K, lattice-K and total-K. The results indicated that potassium fractions were significantly (p = 0.05) affected by different treatments. Different INM modules significantly enhanced significantly K availability in soil. Among various INM modules studied, treatment 11 (application of 20 t ha-1 FYM in maize with 5 t ha-1 FYM every year in chickpea) proved most beneficial for improving the soil K fractions. Findings of this type are important for K fertilizer management during crop production in areas with low soil fertility.

“…Total N content in soil as influenced by various treatments (Table 1) indicated that higher values of N content was obtained from surface soil which could be due to the presence of residues after the harvest of crop as suggested by Kushwaha et al [17] and Singh et al [18]. Further, lowest content found in unfertilized control (676.4, 543.4, 435.7, 221.6 and 110.2 kg ha -1…”

“…The mineralizable N content ranged from 154.4 to 291.3 kg ha -1 in surface soil and from 8.2 (60-75 cm) to 119.3 (15-30 cm) kg ha -1 in sub-surface soil. Increase in mineralizable N indicates that increase in easily oxidizable fraction of organic matter which means increase in availability of N to plant [17]. However, due to addition of fertilizer doses from 100% to 150%, N content was correspondingly improved indicating an impact of fertilizer application on enrichment of N pools [18].…”

“…) and the lowest inorganic N content was obtained in control plot (53.2 kg ha -1 ) without fertilizer application, which directly or indirectly affected the plant growth. Increase in inorganic fraction of N is due to increase in organic carbon in soil which provided more energy source to microbes and also more site for the retention of NH 4 + -N as well NO 3 --N which were replaceable with KCl [17]. Majhi et al [24] reported application of NPK+FYM improved soil fertility by stimulating microbial activity, improving soil physical health, resisting drop in pH to more acidity & improving CEC and macro and micronutrients level.…”

Investigation was made to study the impact of long-term fertilizer and manure application on the sub-soil nitrogen (N) fertility of an acidic Inceptisol under continuous rice-rice cropping system. For this purpose, a long-term fertilizer experiment commenced from 2005-06, rabi season in the Central Farm of Odisha University of Agriculture and Technology (OUAT), Bhubaneswar under aegis of ICAR, New Delhi was used. The experiment had 12 manurial treatments whose impact on sub-soil N fertility up to 75 cm depth and its relation with surface soil N fertility was studied. N uptake and crop yield has been assessed after 20 cropping cycles. The initial soil was acidic (pH 5.8) with low soil organic carbon (4.3 g kg -1) and CEC of 3.75 cmol (p+) kg-1, mineralizable N of 187 kg ha-1 and total N of 1280 kg ha-1. After 20 cropping cycles, the soil organic carbon (SOC) content increased in all the fertilized treatments in the surface layer and with depth it decreased sharply from 15-30 cm to 30-45 cm layer. Treatments with balanced nutrition registered higher content of total N, organic N, mineralizable N and inorganic N both in surface soil and sub-soil. Not only the surface soil but also the sub-soil contents of total N, organic N and mineralizable N are significantly influenced by long-term use of fertilizer nutrients and manure under wet land intensive rice production system. Sub-soil contents of total N, organic N, mineralizable N, inorganic N, ammonium N and nitrate N have strong positive correlation with those of surface layer. SOC, total N, mineralizable N and inorganic N are strongly correlated with each other in the same layer. Correlation of organic N and total N with nitrate N was however, significant up to 30 cm depth and beyond that there was no correlation at 30-45 cm layer. From the results, it is concluded that application of nutrient in balanced and integrated manner (NPK + FYM) not only increased grain yield and sustainability of rice but also improved various pools of N in surface as well as sub-soil up to 75 cm depth of a wet land rice-rice production system under subtropical climatic situation.

“…As a consequence, integrated fertilisation modifies the soil's organic material content, resulting in increased crop yield. Because of improvements in soil physical, chemical, and biological properties, the combined use of chemical fertilisers and organic manure may have increased SOC apart from soil organic matter enrichment, which increased rice yield (Thakur et al, 2011).…”

Conventional method of rice-wheat cropping system leads to deteriorate soil health drastically day by day. An appropriate idea of particular soil health indicator that effects soil health directly should be known to make the crop productivity high. In order to determine the direct and indirect associations among various soil health properties with rice yield in rice-wheat cropping system a survey was done in farmer’s field. Overall 100 soil samples were collected randomly from 100 farmer’s field and studied to find out the soil health. Soil chemical properties (pH, EC, SOC, Avl. N, Avl. P2O5, Avl. K20), Soil physical properties (sand, silt, clay and Available water capacity) and soil biological properties (active carbon, soil respiration and autoclaved citrate extractable protein) were studied to find out the principal indicator for soil health that effects directly to rice yield. The study revealed that mainly soil organic carbon effects rice yield directly along with clay content of soil and soil respiration. Soil microbial activity is also very important in order to achieve good rice yield and positive correlated soil respiration value is evidence of it. Thus the results suggest that farmers should focus on enhancing soil organic carbon and microbial activity by means of soil respiration with best sustainable management practices in order to achieve higher productivity of rice.
