Other soil properties

Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

Maize is a heavy nutrient feeder crop but over and inappropriate fertilization provides lesser yield than the genetic yield potential, lower profits and deterioration in soil health therefore, a new fertilizer recommendation approach, Nutrient Expert (NE) for hybrid maize was evaluated against farmers fertilizer practice (FFP) in three years maize-wheat rotation. Results revealed that nutrient expert-decision support system based nutrient management gave higher yield, nutrient uptake and profits and sustained soil properties over other practices.

Agriculture sector is the most promising sector, dealing with the lot of problems now a day’s one of the innumerable problems is labour unavailability for farming. Other problems or difficulties are extreme weather events, inadequate amount and inefficient application of fertilizer, infection, diseases, allergies and other health problems due to chemical application (fungicide, pesticide, insecticide etc.) or insect/ animal bite. FAO and ITU, together with partners, have been working together in addressing same of the challenges faced in agriculture through the use of sustainable ICTs.

Cluster frontline demonstration (CFLDs) is one of the key extension tools for transfer of technology at grass root level that directly impact the horizontal spread of technology. Pulses play an important role in the food and farming economy of our country. Considering their limited input requirements, soil enriching properties and suitability for growing in areas where moisture (water) is limited, pulses occupy a unique place in our agriculture system.

The brewing industry is one of the largest users of water. Even though substantial technological improvements have been made in the past, it has been documented that approximately 3 to 10 litres of wastewater is generated per litre of beer. Field experiments was conducted at United Breweries (UB) Ltd., Nelamangala and Zonal Agricultural Research Station, UAS, GKVK, Bengaluru in sandy loam soil results revealed that application of 150% RDN through TBWW as 50% basal and 50% in three irrigations recorded significantly higher grain yield (39.6 q ha-1 ) and stover yield (69.

Soil quality is one of the important factors controlling yields of the crops. Soil characterization in relation to evaluation of fertility status of the soils of an area or region is an important aspect in the context of sustainable agricultural production. Soil physicochemical parameters are more important that control its quality. Variation in nutrient supply is a natural phenomenon and some of them may be sufficient whereas others deficient.

n this research work we have inducted the taxonomy from USDA soil taxonomy, as well as extracted the property. More importantly we have done these tasks which are based on regular expression and with the help of connectives. Connective based taxonomy and property extraction helps us not to use huge corpus behind the text processing. In future the framework can be used for other domains in taxonomic text. It may also be extended for the other aspects of ontology learning like identification of axioms and constraints.

A study was carried out in the Department of Soil Science, DRPCAU, Pusa, Bihar during 2014-15 to evaluate physiological properties of Rhizobium isolated from winged bean, pea, gram, lentil and moong. Production of indole acetic acid (IAA), resistance to antibiotics and tolerance to variable pH are some important key concerns for its adaptability to various soil conditions as inoculants. Rhizobia, in general, followed a similar trend towards pH tolerance in terms of growth (measured as OD) i.e., their growth was higher around neutral pH.

Salacia species for its antdiabetic property especially of root, stem and leaf extract. Plant produces several phytochemicals responsible for antidiabetic activity. Four proteins were selected based on literature survey and retrieved from protein data bank. The 18 chemicals were converted into 3 D structure and docked with diabetic protein. Benzeneacetonitrile, .Alpha.-(.Beta.-D-Glucopyranosyloxy)- ,(R)- is a chemical expressed in salacia which showed good antidiabetic property among 18 other chemicals.
