Imbalanced use of nutrients through fertilizer have a deleterious effects on soil health, leading to unsustainable productivity. The present investigation was carried out to study the comparative effectiveness of compost and crop residue either alone or in combination of chemical fertilizer on physico chemical properties of soil, soil microbial biomass and crop yield in rice-wheat cropping system in Calciorthents at experimental farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar in light texture and medium fertile soil. There were sixteen treatments which were replicated thrice in split plot design. Four level of NPK viz., no NPK, 50% NPK, 100% NPK and 150% NPK were kept as main plot treatments whereas four levels of organics viz., no manure, compost @ 10 t ha-1, crop residue and compost + crop residue were treated as sub-plot treatments. The correlation between rice yield and some physico-chemical and microbial attributes of soil were evaluated. Most of soil physical, chemical and microbiological parameters were positively correlated with grain and straw yield of rice. Thus the results suggest that integrated use of balanced inorganic fertilizers in combination with organic manure sustains a soil physico-chemical and microbiological environment of soil that is better for enhancing higher crop productivity.

A balanced application of organics and inorganic fertilisers could be beneficial to both soil nutrient availability, soil health and crop growth. The experiment was conducted on light textured highly calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa. Four levels of inorganic fertiliser treatments were applied i.e. 50, 100 and 150% of NPK along with no NPK as control as main plot treatments while four levels of organic treatment (i.e. no organics, compost, crop residue and compost+ crop residue) were applied as sub plot treatments in a split plot design with a total sixteen (16) treatments with three replications to investigate the long term effect of application of various doses of recommended fertiliser along with organic amendments on various physico-chemical properties of calcareous soils after 32nd crop cycle . Data was collected on various physico-chemical properties i.e. Soil pH, electrical conductivity (dSm-1), soil organic carbon (g kg-1), free CaCO3 (%), cation exchange capacity [cmol (p+) kg -1], bulk Density (Mg m-3) and water holding capacity (w/w %). The result revealed that soil pH was reduced by 3.9% while electrical conductivity (EC) was reduced by 45% over initial (1988). Both soil pH and EC were reduced by 1.7% and 15.4% respectively in plots receiving combined application of compost and crop residue along with 150% NPK over control. Organic carbon was improves by 33% over initial (1988) which had direct effect on reduction in soil bulk density (32%) and improved water holding capacity (29%) over the control in plots receiving 150% NPK along with combined application of compost and crop residue. Soil cation exchange capacity and free CaCO3 also showed an alternate trend former being enhanced and later being reduced after 32nd crop cycle in rice-wheat cropping system. Application of different levels of NPK along with different organics improved the overall soil physico-chemical properties which further have direct relation with enhanced crop growth and productivity.

(2011-2012 and 2012-2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laid out in a randomized block design in kharif seasonwith four treatments. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. Data collected on soil physico-chemical properties after harvest of maize crop were relatively improved with the application of 100%NPK in combination with FYM @10t ha-1 to preceding rice crop, irrespective of the NPK levels applied to succeeding maize crop. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

Basic Cations

Acidic soils limit the production potential of crops because of low availability of basic cations and excess of hydrogen (H+) and aluminium (Al3+) in exchangeable forms. In the western part of the country such as Assosa and Wellega, soil acidity is a well-known problem limiting crop productivity. A field study was conducted to assess the effects of lime, vermicompost and their combinations on selected soil physico-chemical properties and responses of soybean grown on acidic Nitisols of Assosa area during 2016 and 2017 main cropping seasons. Soil samples were collected from the experimental site before planting and from plots after harvesting. The collected samples were analysed following the standard methods for soil physico-chemical analysis. The treatments were factorial combinations of four levels of lime (0, 1.62, 3.62 and 4.90 t ha-1) and four levels of vermicompost (0, 1.50, 3.00 and 4.50 t ha-1). The results revealed that soil pH increased from 5.31 – 5.86 pH while exchangeable acidity decreased from 5.46 - 2.85 cmol (+) kg-1 with levels of lime and vermicompost (3.26 with 3 and 4.90 with 4.5) t ha-1 respectively, which resulted in improved soil physico-chemical properties. The combined application of lime and vermicompost also significantly improved the yield related parameters of soybean. The maximum grain yield (1.95t    ha-1) was obtained from the combined application of 4.90 ton lime and 3.00 ton vermicompost ha-1 followed by combined application of 3.26 ton lime with 3.00 ton vermicompost ha-1 with non-significant variation. Therefore, the combined application of 3.26 ton lime and 3.00 ton vermicompost ha-1 is a promising alternative amendment for amelioration of acidic Nitisols of Assosa (Amba-12 Kebele) and other similar agro-ecologies for the improvement of soybean production.

A field experiment was conducted during the Kharif and Rabi seasons of 2001-2005 in regular crop sequence at Crop Research Station, Nawabganj, CSA University of Agriculture & Technology, Kanpur in order to find out the effect of farm yard manure (FYM) and NPK levels in rice-wheat cropping system. One level of FYM (10 t ha-1) and one level of N (120 kg ha-1),three levels of P (0, 30, 60 kg ha-1), four levels of K (0, 30, 60, 90 kg ha-1) were tested. The grain yield of rice and wheat crops were increased at levels of FYM (10 t ha-1) and NPK (120, 60, 60 kg h a-1). The application of FYM with 120 kg N, 60 kg P O and 60 kg K O ha-1 gave significantly highest yield of rice and wheat crops. The 2 5 2 application of NPK fertilizers with FYM were found increased in their uptake. The application of NPK fertilizers with FYM was found improvements in physio-chemical properties of soil like soil ph, organic carbon and available NPK.

Nutrient management influences soil health and crop productivity. Sustained crop production re-quires specific nutrient management options after a certain period. The objectives of this investigation were to examine the effects of inorganic and organic fertilization on yields and soil carbon budget under rice based cropping patterns in Bangladesh. The research data and informationhave been gen-erated based on previouslypublished, unpublished sources and own concept.Omission of K or im-balanced K are more influential for reduction in grain yield up to 47% in Boro (dry) season but N was most limiting up to 35% in T. Aman (wet) season. With existing fertilizer rates for growing rice, the balances of N and K are always negative. Balanced chemical fertilizer (NPKSZn) can be an option for improving crop productivity and maintain soil quality. Net ecosystem carbon (C) balances are posi-tive when 3 t ha-1 cow dung (CD), 2 t ha-1 poultry manure (PM) and 2 t ha-1 vermicompost (VC) are used in combination with chemical fertilizers. Soil amendments with organic nutrient sources (rice straw, CD, PM, VC, legume crops) and rice based cropping patterns such as T. Aman-Mustard-Boro, Boro-Fallow-Fallow, Jute-T. Aman-Fallow, Wheat-Mungbean-T. Aman, Grass pea- T. Aus-T. Aman and Potato-Boro-T. Aman can be beneficial in improving soil C budget, soil nutrient ratio, total crop production and maintenance of environmental health that will meet SDGs goal.

The Impact

The present study was conducted to explore the role of different types of vermicomposts (VCs) prepared from different substrates to improve soil health (physical and chemical properties) and wheat plant growth under field conditions. Different combinations of vermicompost prepared from different substrates (cow dung, paper waste, and rice straw) and inorganic fertilizers were applied in soil using wheat as a test plant. The impact of three different VCs on physico-chemical characteristics and nutrient availability in soil was evaluated to examine their efficacy in combination with chemical fertilizers. Temporal trends in vermicomposting treatments at various stages showed significant improvement in physico-chemical attributes of the VCs substrates. All the plant physiological attributes showed significant response where N:P:K 100:50:50 kg ha−1 + 10 t ha−1 cow dung vermicompost was applied. In addition, post-harvest analysis of soil not only revealed that different combinations of the vermicomposting treatments improved the soil health by improving the physico-chemical attributes of the soil. Conclusively, application of cow dung vermicompost along with recommended NPK not only improved crop yield, soil health, reduced insect (aphid) infestation but also fortified grains with Zn and Fe.

Understanding of the potassium (K) nutrient cycle and its microbial transformation of unavailable forms of soil K to plant-available K is crucial in any agroecosystem for strategic nutrient management through inorganic fertilizer, crop residue (CR), and microbial applications. Therefore, the present investigation was undertaken to study the effect of crop residue and K management practices on crop productivity, K mobilization from native soil K-pool, and crop assimilation of K under a zero-till maize–wheat cropping system. The experiment consisted of four residue levels (0, 2, 4, and 6 Mg ha−1) and five K levels (0, 50%, 100%, 150% RDK [recommended dose of K] and 50% RDK + potassium solubilizing bacteria, KSB). Results showed that CR retention at 6.0 Mg ha−1 significantly improved grain yield (of maize by 10.17%; wheat by 9.87%), dry matter accumulation, K uptake and redistribution in native soil K pools (water soluble K (WSK), exchangeable K (EK) and non-exchangeable K (NEK)) at 30 and 60 days after sowing and at harvest as compared to no CR. Among the K management, 50% RDK+KSB reported significantly higher grain yield (of maize by 26.22%; wheat by 24.70%), dry matter accumulation, K uptake, and native K pools (WSK, EK, and NEK) at different growth stages compared to no K. Total K did not differ significantly due to residue and K management. The highest actual change of K reported with 6.0 Mg ha−1 CR (51 kg ha−1) and 50% RDK+KSB (59 kg ha−1) over control. Significant (p ≤ 0.01) positive correlation was found among grain yield, dry matter accumulation, K uptake, the actual change in K and different native K pools. It can be concluded that retention of 6 Mg ha−1 CR and supply of 50% K through inorganic fertilizer along with seed inoculation of KSB biofertilizers, improved crop growth, productivity by enhancing K assimilation as a consequence of the release of non-exchangeable K and through the application of CR and K treatments under a zero tillage maize–wheat system.

The study was carried out to investigate the yield and soil quality of wheat (Triticum aestivum L.) and moong (Vigna radiate L.) crop. In order to obtain high precision in the results of the present investigation, the research trials were conducted for two consecutive years 2008-09 and 2009-10 under field conditions at Artoni (Agra) site. The experiment was laid out in RBD with five microbes (Azospirillum, Azotobactor, PSB, Azolla and Rhizobium) and four levels (120 and 60 kg N for wheat and 25 and 10 kg N for moong crop) of nitrogen. The results of this experiment proved that T2 treatment (Azospirillum +60 kg N ha-1) showed the best outcome during both the years for wheat crop and in moong crop. The growth and yield parameters i.e. plant height, no. of branches plant-1 no. of pods plant-1, pod length and grain yield were observed and treatment T7 (Rhizobium +10 kg N ha-1) was found to be better combination than others. The soil in respect to its physico-chemical properties showed an improvement due to the use of biofertilizers when compared to control and farmers practice.

Soil physico-chemical properties are an important phenomenon for sustainable crop production and maintenance of optimum soil health. Hence, a laboratory measurement was conducted with soil samples of three years long experimental field of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh to assess the changes in five selected soil physico-chemical properties viz. soil texture, bulk density, soil pH, total nitrogen and organic matter. The experiment was laid out in a split plot design with two water regimes (continuous flooding and alternate wetting & drying) in the main plots and five fertilizer treatments (N0 - control, N1- 140 kg N/ha as PU, N2- 104 kg N/ha as USG (2× 1.8 g/ 4 hills), N3 - 5 t CD + PU @ 140 kg N /ha on IPNS basis and N4- 5 t CD + USG (2× 1.8 g/ 4 hills @ 104 kg N/ha)) in the subplots under rice-rice cropping pattern with three replications. After three years, soil samples were collected at 0-5 and 5-10 cm soil depths for measuring bulk density and at 0-10 cm depth for other soil properties and analyzed. Results found that % sand, % silt, % clay, bulk density and soil pH was not changed significantly compared to initial status. Percentage of total nitrogen and organic matter was significantly affected by irrigation and fertilization. Total nitrogen (%) was higher in AWD whereas organic matter (%) was higher in CF practice. The highest total nitrogen (%) and organic matter (%) was found in N4 treatment in which USG was applied in combination with cowdung as organic manure. It can be suggested that N4 treatment was formed good combination for sustaining chemical properties of soil. Further long- term experimentation will be needed to know the changes in soil properties for sustainable crop production and improving soil health. Asian Australas. J. Biosci.
