The use of resource management technologies such as zero tillage, which can affect the soil properties, can restore soil health that is degrading at a rapid pace due to intensive agriculture, inefficient and imbalanced use of fertilisers, high-yielding crops, the use of heavy machinery, excessive tillage, etc. The health of the soil can be measured by the capacity of microorganisms that can act as early warning signals. To improve soil quality, zero tillage is recommended globally and has significant effects on soil microbial communities.

In this chapter, physiological responses of oleaginous fungi such as, biomass production, substrate uptake, secretion of hydrolytic enzymes, and lipid accumulation with cellulose or starch as the organic carbon substrate were studied. Glucose, one of the simplest sugars, was also studied as a comparison study. M. rouxii, a known lipid and GLA producer (Ahmed et al., 2006), was used in this study.

The present investigation was carried out to assess the impact of different jute based cropping systems on soil quality in farmers’ fields. Soil samples (georeferenced) were collected at 0-0.2 m depth from the farmers’ fields following the jute based cropping systems for more than five years. Soil quality was evaluated in terms of physico-chemical and biological attributes of soils.

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 experiment was conducted to assess Microbial biomass carbon and Nitrogen on 84 days organic and conventional incubated soils in Nadia district of West Bengal. Soil microbial biomass carbon & nitrogen is determined by Chloroform Fumigation Extraction method (FE) followed by Kjeldal Digestion method. The results depicted that, microbial biomass carbon and nitrogen was more in organic soil of Phulia and Gayeshpur district rather than conventional method.

The study of soil microbial dynamics is a matter of importance as microbial activities controls soil carbon(C) and nutrient dynamics. This study focused on soil C budgeting under forest and cultivated lands as land use affect soil C and microbial dynamics. The soil samples were collected from Rasomoti and Sonapur forest range along with the agricultural fields of the neighbouring areas. Among soil microbial parameters, microbial biomass C and soil respiration were studied.

A field experiment was conducted during 2015-16 at Agricultural Research Station, Mudhol, University of Agricultural Sciences, Dharwad to evaluate different methods of irrigation to achieve higher target yield levels in sugarcane. The experiment was laid out in split plot design with 12 treatment combinations and three replications. Among the irrigation methods, subsurface (224 t ha-1 ) and surface drip irrigation (217 t ha-1 ) recorded significantly higher cane and sugar yield.

A field experiment was conducted during Kharif season 2015. The results of the study indicated the application of phosphorus up to 40 kg P2O5 ha-1 recorded significantly higher number of pods per plant, number of seeds per pod and seed and straw yield, nitrogen, phosphorus and potassium uptake in seed and straw, protein content in seed, microbial biomass carbon, nitrogen and phosphorus in soil as compared to absolute control and 20 kg P2O5 ha-1 but was at par with 60 kg P2O5 ha-1 .

A field study was carried out on Alluvial soils of Varanasi to analyse the short term impacts of replacing mineral by organic fertilizers on the physico-chemical properties and enzyme activities relevant for soil fertility and crop production. Three types of fertilization regimes were tested viz., no fertilizer, conventional as 100% RDF by inorganic fertilizer and combined integrated fertilizer in which 70% RDF with 30% of the nitrogen were supplied by either FYM or pressmud or vermicompost or combination of these two or all.

A field experiment was conducted during kharif season 2015 in alluvial soil at farmer field, in village Loharapur, Varanasi, to study the soil microbial biomass, dynamics and selected enzyme activities as influenced by farm yard manure and inorganic fertilizer. The soil microbial biomass carbon; nitrogen and phosphorous was improved significantly with the different treatments. Highest soil biomass carbons, nitrogen, phosphorous were recorded with the combined application of inorganic nutrients and farm yard manure (T7) over the remaining other treatments.

The average concentration of particulate organic carbon (POC), dissolved organic carbon (DOC) and microbial biomass carbon (MBC) in organic manure plus inorganic fertilizer treatments (NP+S and NP+FYM) in 0–60 cm depth were increased by 64.9–91.9%, 42.5–56.9%, and 74.7–99.4%, respectively, over the CK treatment. Accumulation of crop residues and organic matter in the surface layer under conservation tillage creates favourable feeding conditions and also provides physical protection to various soil organisms, thereby increasing their abundance as well as diversity.

Soil organic carbon (SOC) and its fractions (labile and non-labile) including particulate organic carbon (POC) and its components [coarse POC and fine POC], light fraction organic carbon (LFOC), readily oxidizable organic carbon, dissolved organic carbon (DOC) are important for sustainability of any agricultural production system as they govern most of the soil properties, and hence soil quality and health.

A field study from 2009 to 2013 was carried out to investigate the effect of organic manure including panchagavya and biodynamic spray on commonly used tomato-coriander-pea and cauliflower-cauliflower-peacropping system in Western Himalaya. The results revealed that cropping systems differ significantly in terms of soil microbial properties. The tomato-coriander-pea crop sequence recorded higher soil carbon biomass and population of soil bacteria, fungi and actinomycetes as compared to cauliflowercauliflower-pea crop sequence.

Role of vermicompost in nourishing agricultural crops has attracted the attention of researchers throughout the globe in past few decades. Vermicompost is the method of using earthworms to transform organic waste into nutrient rich compost. The earthworms’ casting is nutritive organic manure rich in humus, NPK, micronutrients, beneficial microbes, antibiotics, enzymes, growth hormones, etc. There are many reports in literature showing beneficial effects of imbedding vermicompost in soil.
