Soil quality index

The paper "Aggregate indices method in soil quality evaluation using the relative soil quality index" presents a new approach to assess the soil quality by aggregate indices using the Relative Soil Quality Index (RSQI) proposed by Ho Ngoc Pham. RSQI is integrated from the individual indices into a simple formula for overall assessment of the soil quality. RSQI is different from other approaches.

Impact of fly ash (FA) on germination and initial seedling growth performance of Acacia auriculiformis was studied. Growing media was prepared by mixing FA to forest soil (S) at five concentrations 20%, 40%, 60%, 80% and 100% (w/w). The experimental design was CRD with six treatments and three replications. Freshly collected seeds were treated with warm water followed by cold water and sown at 1.0-2.0 cm depth in germination trays filled with media of different treatments. Significant (P

The quality of land development/ levelling is having enormous impact on soil moisture storage and distribution in the field both spatially and temporally, crop growth, yields and irrigation water saving. So, unevenness of agricultural fields leads to the in-efficient use of irrigation water, which in turn reduces the yield and farm income. The quality and accuracy of land levelling determined by term “Levelling index” (LI) are dynamic factors. Consequently, it is imperative to study the impact of levelling indices on soil moisture distribution in fields.

Land development is one of the prime components of sustainable farming. Unevenness of agricultural fields leads to the in-efficient use of irrigation water, which in turn reduces the yield and farm income. Levelling index, which is a dynamic factor, determines the quality and accuracy of land levelling. Land development/levelling is having enormous impact on moisture storage and distribution in the field both spatially and temporally, crop growth, yields and irrigation water saving.

Soil quality assessment is of paramount importance to know the appropriate management practices to be adopted for sustainable crop production. Sustainability of intensive agriculture system is intimately linked to maintenance of soil health. Present study was undertaken to investigate the impact of intensive cultivation on soil health under polyhouses located in Bilaspur, Solan and Sirmaur districts of Himachal Pradesh. Studies reveal that the bulk density ranged from 1.09 to 1.13 Mg m-3 .

Conservation agriculture (CA) is based on principles of minimum soil disturbance through zero or minimum tillage operations, residue retention on soil surface and crop diversification which not only improves healthy functioning of soil but also enhances nutrient availability, its biological quality and aggregate formation. On the other hand, conventional tillage (CT) practices characterized by excessive tillage, residue removal and monoculture are often associated with the degradation of soil mainly in terms of depletion of Soil Organi arbon (SOC), sub-soil compaction and loss of biodiversity.

The study was conducted to assess soil quality in cotton growing environs of Nilona micro-watershed in Yavatmal district, Maharashtra, covering mainly cotton growing areas. One hundred eighteen surface soil samples were identified for determining physical and chemical indicators of soils. A minimum dataset was developed using expert knowledge for identifying soil quality indicators. Soil quality was determined using concept of relative soil quality index (RSQI).

Gladiolus is a very popular flowering plant grown for its elegant cut spike. Presently, the Gladiolus corms are planted manually which is time and labour intensive process. It also involves considerable amount of drudgery. Till date very little work on mechanized planting of corms has been reported. In order to carry out the panting operation in specific time and to mechanize this operation for Gladiolus crop, a cup-chain type metering mechanism was developed and its performance was evaluated in linear soil bin.

‘Seed balls’ are prepared by non-governmental organizations and enthusiastic school children to trees grow trees rapidly for ecosystem restoration. However, there is immense scope for technically improving the seed balls by ensuring the quality of seeds as well as media; further preparing cuboid structures, instead of ball like structure has immense scope in facilitating rooting of the newly emerging seedlings. Against this back drop, a series of experiments were conducted to standardize the seed coating technique, seed priming method and appropriate media for making seed cubes.
