“…farm yard compost (FYC), were used in A1, these were applied at a rate of 4 ton/hectare as a basal dose before sowing and Jivamrit-S [11], a concoction consisting of cow dung, cow urine, jaggery, gram flour, and soil; fermented for certain period, were also applied with watering twice, at a seven-day interval from sowing. This concoction/jivamrit S was prepared in composting pits [12]. The same fertilizer application was maintained for all seasons.…”

“…The integrated amended fields had a basal dose of farm yard manure (FYM) (applied at a rate of 1 ton/ha) and synthetic fertilizers as sources of Nitrogen and Phosphorus. Nitrogen based fertilizer urea (Brand Kisanmodified) was applied at a rate of 60 kg/ha as the top dressing at around 15-20 DAS (days after sowing) and Di ammonium phosphate (DAP) (Brand Kisan modified)as phosphorus source at the rate of 40-60 kg/ha was applied as the top dressing at around 15-20 DAS [12].…”

“…Only those farms were selected that followed same amendment practices for past 6 years. The sites for the experiment grew the crops wheat (Triticum aestivum) and castor (Ricinus communis) crops as Rabi (winter) and maize (Zea mays) and sorghum (Sorghum bicolor) as Kharif (summer); depending on the monsoon.Monoculture cropping pattern with minimal mechanization, where both types of fields used tractors only for ploughing purpose was adapted [12]. In all the three phases of crop, four different samples were collected per ha per field and were further pooled to form one composite sample.…”

“…Analysis of these composite samples was carried out in triplicate. Soil samples were divided into two parts.First part of the sample was air dried in shade, sieved through a sieve size of 2 mm, and analyzed for physical and chemical characteristics, and the second part of this soil sample was stored at 4˚C for further microbiological analysis (12). For each crop season three phases were chosen: the initial, mid-, and post-harvest phases.…”

Amongst the soil qualities that are taken into consideration while quantifying the fertility status of soil for agri-production, the properties of water holding capacity, bulk density, electrical conductivity and soil pH play crucially important roles, directly as well as indirectly. The role of organic matter content of soil in altering the aforesaid properties occurs through various complex interactions. In our study we attempted to understand the impact of amendments in traditional ecological knowledge (TEK)-based organic input agri-management systems (A1), versus conventional chemical-intensive agri-systems (A2) in altering/modifying the few important properties viz soil organic matter (SOM), pH, electrical conductivity (EC), bulk density, and water holding capacity of the soil in the three different crop phases viz. pre, mid and the post-harvest, spread over six cropping seasons in four years. The study area was a geo-ecologically unique terrain of Kachchh, Western India. Natural stressors as erratic rainfall, drought and salinity are a typical feature of this zone. Physico-chemical soil attributes have shown significant differences in the amendment systems. The application of organic manures and concoctions like Jivamrit from indigenous knowledge base of local farming community, certainly rendered better organic matter content that affect soil structure and stability, which in turn affected the maximum water holding capacity (MWHC), which was significantly higher in A1 (47.53%; (Standard Error [SE] = ±0.92%) across phases and seasons than A2 (37.99%; SE = ±0.74%). Probably, for the same reason, amendments with organic inputs had a lower bulk density (1.04 g/cm3; SE = ±0.02 g/cm3) as compared to amendments with no or very few organic inputs (1.31 g/cm3; SE = ± 0.03 g/cm3).The reduction in pH and electrical conductivity in A1 may be ascribed to increased amounts of SOM as a result of addition of green manures and organic concoctions. Even during the stressed period of drought in cropping seasons of season 2 (Kharif2012) and season 3 (Rabi 2012–2013) this trend was followed. This clearly shows that salinity endurance and drought resistance are remarkable features of organically amended soils and this resilience to drought is achieved over continual usage of organic manures. The arid and semi-arid tropics are highly prone to stressors like drought, highly erratic rainfall patterns, and salinity, and the present study advocates the supremacy of TEK-based agri-management systems in soil sustainability for maintaining the soil fertility in the long run.

The major crop nutrients determine the nutritional content and vigor of crops. The deficiency or occurrence below minimal level of any of the nutrients are often seen as a cause of poor growth or complete crop failure. The present study was an attempt to understand the impact of Traditional Ecological Knowledge (TEK) (A1)vis-à-vis conventional chemical intensive (A2)agriculture amendment systems in altering/modifying the nutrient dynamics of the soil with respect to nitrogen (N), phosphorus (P), potassium (K) and sulphur (S), calcium (Ca), magnesium (Mg) levels in the pre, mid and post-harvest phases of crop in six cropping seasons spread across four years. The study area was a geo-ecologically unique terrain of Kachchh, Western India, a typical representative of allied arid and semi-arid tropics that are prone to various natural threats and stressors like drought, salinity and erratic rainfall pattern that affect the agri-management activities. Seasonal amendment data, clearly depicts that TEK based systems were efficient in soil organic carbon (SOC) accrual over seasons, an important trait required in challenging settings of tropical aridisols. The major primary (N, P, K) and secondary (S, Ca, Mg) nutrients were at par or higher than integrated chemical intensive systems. TEK based amendments ensured proper and timely management of nutrients in the soil. This inherent value addition offered by indigenous manure applications is an important step in climate change mitigation measures and overall agricultural sustainability.
