Long‐Term Land‐Use‐Driven Changes in Nutrient Storage (Macro and Micro), Biological Health, and Carbon Pools in the Eastern Himalayas, India
Long‐term land‐use transitions significantly alter soil nutrient dynamics, microbiological functions, and carbon (C) pool distributions in the soil profile. This study assessed the long‐term effects of converting a 50‐year‐old primary forest into cultivated land‐use systems, namely, agriculture (AGLU), horticulture (HOLU), and agroforestry (AFLU), over a period of 20–26 years in the Eastern Himalayas, India. The soil was taken to a depth of 1.0 m…
Assessment of Organic Carbon Stock and Soil Organic Carbon Fractions Across Different Cropping Systems in the Red and Laterite Soils of Meghalaya, India
Soil carbon (C) depletion is a prime indicator of land degradation. Cropping system intensification with short‐duration legumes is a perceived important strategy to restore soil C in agricultural land. Hence, the impact of six cropping systems (maize [ Zea mays ]—French bean [ Phaseolus vulgaris ], maize–soybean [ Glycine max ], maize–urdbean [ Vigna mungo ], maize–mungbean [ Vigna radiata ], maize–toria [ Brassica campestris var. toria], and mai…
Can biochar conserve soil moisture and improve soil properties for sustainable intensification of acid soils in the Eastern Indian Himalayas
The marginal Himalayan ecosystems have great potential for biochar application for conserving soil moisture, ameliorating soil acidity, improving soil fertility, and thus, contributing to sustainable intensification. Thus, the efficacy of biochar was tested along with nutrient management practices (NMP) on the performance of maize ( Zea mays L.)‐French bean ( Phaseolus vulgaris L.) as the emerging cropping system in an acid soil under rainfed hil…
Liming and micronutrient application improves soil properties and productivity of the groundnut‐rapeseed cropping system in an acidic Inceptisol of India's eastern Himalayas
Aluminum toxicity, nutrient imbalance, and reduced microbial activity are the most limiting factors for optimum agronomic productivity in acid soils. A field study was conducted to investigate the impact of micronutrient and liming on soil properties and productivity of groundnut‐rapeseed system in an acidic Inceptisol. The impact of six micronutrient (control or no micronutrient, Zn at 5 kg ha −1 , B at 1 kg ha −1 , Mo at 0.5 kg ha −1 , Zn + Mo,…
Improved agronomic practices and high yielding rice varieties maintain soil health and enhance yield and energy use efficiency under shifting cultivation landscapes of eastern Himalayas
Low productivity, depletion of soil fertility, and inefficient energy use are the major challenges of fragile Jhum (shifting cultivation: 280 M ha worldwide) agro‐ecosystems in north eastern Himalaya. Farmers' participatory field trials were conducted in sloping lands of Meghalaya, India over 3 years to identify suitable agronomic management practices and input responsive rice genotypes for sustaining soil health and enhance carrying capacity of …
Managing rice fallow lands of the Eastern Indian Himalayas
Degenerating soil properties, low diversification, and productivity are the major issues for keeping large areas as fallow after rainy season rice ( Oryza sativa L.) in Southeast Asia. Long‐duration rice cultivars along with conventional till farming and lack of irrigation facilities limit the chances of growing succeeding crops like pulses in rice fallow areas. Therefore, a field study was conducted to test the hypothesis that cultivating short‐…
Conservation tillage and residue management improves soil properties under a upland rice–rapeseed system in the subtropical eastern Himalayas
Poor soil properties and low soil moisture content (SMC) are major limitations for cultivating a second crop after the rainy season rice ( Oryza sativa L.) in the uplands of the Eastern Himalayas. Information on impact of conservation tillage and residue management (RM) to alleviate soil constraints is limited in the region. Thus, a field study was conducted in a rice–rapeseed ( Brassica campestris Var. Toria) system under rainfed conditions with…
Seaweed sap
The average productivity of Maize in the north-east hill region of India is very low (1.50 t/ha) mainly owing to cultivation under nutrient-starved conditions. Practical technologies have been developed to cultivate two commercially important seaweeds, viz. Kappaphycus alvarezii and Gracilaria edulis in tropical waters. The sap of these seaweeds has turned out to be a low-cost potent plant biostimulant when applied as foliar spray. A field experi…
