Soil Fertility Status

Agriculture is both affected by climate change but also contributes to it. As a sector, agriculture must therefore both adapt to changes and offers options for mitigation ie reducing greenhouse gas emissions and store carbon. The objective of the study is to explore the optimum level of plant nutrient for sustaining the desired crop productivity in hybrid cotton through optimization of benefit from all possible resources of plant nutrients in an integrated manner and to mitigate the green house gas emission through the adoption of Integrated Plant Nutrition System. The experiment was carried out in three locations with different soil fertility status with special emphasis to nitrogen levels in the soils. The fertilizer doses were fixed based on the soil test values and fertility grouping / indexing by International soil fertility evaluation and improvement programme. As part of organics, FYM was applied at two different levels, and the fertilizers were reduced accordingly. The results proved that application of organic manure @ 12.5 t ha-1 along with the recommended doses of nutrients proved superior in seed cotton production as well reduced nitrous oxide emissions.

Rapid Urbanization

Increasing pressure on farming systems due to rapid urbanization and population growth has severely affected soil health and fertility. The need to meet the growing food demands has also led to unsustainable farming practices with the intensive application of chemical fertilizers and pesticides, resulting in significant greenhouse gas emissions. Biochar, a multifunctional carbon material, is being actively explored globally for simultaneously addressing the concerns related to improving soil fertility and mitigating climate change. Reviews on biochar, however, mainly confined to lab-scale studies analyze biochar production and its characteristics, its effects on soil fertility, and carbon sequestration. The present review addresses this gap by focusing on biochar field trials to enhance the current understanding of its actual impact on the field, w.r.t. agriculture and climate change. The review presents an overview of the effects of biochar application as observed in field studies on soil health (soil’s physical, chemical, and biological properties), crop productivity, and its potential role in carbon sequestration. General trends from this review indicate that biochar application provides higher benefits in soil properties and crop yield in degraded tropical soils vis-a-vis the temperate regions. The results also reveal diverse observations in soil health properties and crop yields with biochar amendment as different studies consider different crops, biochar feedstocks, and local climatic and soil conditions. Furthermore, it has been observed that the effects of biochar application in lab-scale studies with controlled environments are not always distinctly witnessed in corresponding field-based studies and the effects are not always synchronous across different regions. Hence, there is a need for more data, especially from well-designed long-term field trials, to converge and validate the results on the effectiveness of biochar on diverse soil types and agro-climatic zones to improve crop productivity and mitigate climate change.

Soil Fertility Status

The present study was undertaken to quantify changes in the status of soil nutrients, their depletion and build-up after continuous long intensive cropping for last 36 years in a permanent manorial trial which has been in progress since 1972 in an alfisol of western Himalayas. The rotation was maize-wheat which included various combinations of N, P, K, Zn and FYM (farmyard manure). Continuous cultivation influenced pH, OC (organic carbon), available N (nitrogen), P (phosphorus) and K (potassium). An increase in the status of organic carbon was observed in 100% NPK + FYM treatments for more than three decades from initial value of 7.9 to 12.0 g/kg. The use of either FYM or lime alongwith 100% NPK sustained crop productivity or improved nutrient status. However, imbalanced use of nutrients i.e. NP or N alone is adversely affecting the fertility of soil by aggravating the problem of soil acidity. Application of S free P fertilizer DAP (diammonium phosphate) drastically reduced the yield of both the crops. Thus, continuous use of balanced fertilizers is necessary for sustaining soil fertility and productivity of crops.

In recent years much attention has focused on the impacts of agriculture on climate change, due to this stage specialists in plant nutrition and soil fertility have achieved the task of generating adequate fertilization doses for pineapple. A methodology for Integrated System for Recommending Fertilizer Dose, was used. As a result, seven Thiessen polygons, where rainfall ranged from 1640 to 2841 mm was correlated. Therefore, three major soil groups were defined and classified as subunit level. Likewise, eight doses of fertilizers were generated as follows: N, P2O5 and K2O, with a fertilizer dose, a map is generated according to the cultivar: 230-138-300 for Creole pineapple Acrisol Cutánico (Chromic, Ferric); 460-161-480 for Cayenne and MD2 in Acrisol Cutánico (Endoarcíllico, Ferric); 345-161-450 for Cayenne and MD2 and Creole in Acrisol 253-138-450 for Cutánico (Endoarcíllico, Hyperdystric, Ferric); 391-161-450 for Cayenne and MD2 in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric) and Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric, Ferric); 207-138-300 for Creole in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric); 253-138-300 for Creole in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric, Ferric); 253-138-360 for Creole in Acrisol Umbric Gleyic (Hyperdystric, Ferric); and 391-161-360 in Endogleyic Cambisol (Clayic, Eutric). These fertilizer doses were supplemented with micronutrients to obtain the expected results.

Abstract Key message Climate change and Genotype-by-Environment-by-Management interactions together challenge our strategies for crop improvement. Research to advance prediction methods for breeding and agronomy is opening new opportunities to tackle these challenges and overcome on-farm crop productivity yield-gaps through design of responsive crop improvement strategies. Abstract Genotype-by-Environment-by-Management (G × E × M) interactions underpin many aspects of crop productivity. An important question for crop improvement is “How can breeders and agronomists effectively explore the diverse opportunities within the high dimensionality of the complex G × E × M factorial to achieve sustainable improvements in crop productivity?” Whenever G × E × M interactions make important contributions to attainment of crop productivity, we should consider how to design crop improvement strategies that can explore the potential space of G × E × M possibilities, reveal the interesting Genotype–Management (G–M) technology opportunities for the Target Population of Environments (TPE), and enable the practical exploitation of the associated improved levels of crop productivity under on-farm conditions. Climate change adds additional layers of complexity and uncertainty to this challenge, by introducing directional changes in the environmental dimension of the G × E × M factorial. These directional changes have the potential to create further conditional changes in the contributions of the genetic and management dimensions to future crop productivity. Therefore, in the presence of G × E × M interactions and climate change, the challenge for both breeders and agronomists is to co-design new G–M technologies for a non-stationary TPE. Understanding these conditional changes in crop productivity through the relevant sciences for each dimension, Genotype, Environment, and Management, creates opportunities to predict novel G–M technology combinations suitable to achieve sustainable crop productivity and global food security targets for the likely climate change scenarios. Here we consider critical foundations required for any prediction framework that aims to move us from the current unprepared state of describing G × E × M outcomes to a future responsive state equipped to predict the crop productivity consequences of G–M technology combinations for the range of environmental conditions expected for a complex, non-stationary TPE under the influences of climate change.
