“…In comparing the tillage systems, tillage reversal (NT-CT, RT-CT) and RT had significantly higher available potassium than NT. Other studies have also reported similar effects of tillage and organic manure application on available K in soil [58,59]. This result was explained by the mineralization of this element resulting from mechanical incorporation and mineralization of crop residues, fertilizers, and FYM in the NT-CT, RT-CT, and RT treatments and agree with those reported by [60,61].…”

Effect of conservation tillage on crop performance and soil properties has been studied extensively under different agro-climatic situations. However, the impact of reversal from conservation tillage to conventional tillage on crop growth and soil nutrient release is rarely addressed. Thus, this study was conducted by converting half of the eight years old conservation tillage experiment to the conventional one with a similar level of residue return to compare the effect on soil nutrient availability and nutrient uptake in soybean crops in the Vertisols of Central India. The conservation tillage treatments included no-tillage (NT) and reduced tillage (RT) with 100% NPK (T1), 100% NPK + farmyard manure (FYM) at 1.0 Mg-carbon (C)/ha (T2), and 100% NPK + FYM at 2.0 Mg-C/ha (T3). After eight years of the experiment, the RT and NT treatments were subjected to conventional tillage, and thus the tillage treatments were RT-CT, RT, NT, and NT-CT. After tillage reversal for three growing seasons, soybean yield and nutrient uptake (N, P, K) got significantly influenced by the tillage and nutrient management. Averaged across nutrient treatments, NT showed highest soil organic carbon (SOC) content (8.4 g/kg) in the surface 0–5 cm layer. However, at 5–15 cm depth, the SOC was greater in the RT-CT treatment by 14% over RT and by 5% in the NT-CT treatment over NT. The soil nutrient availability (N and P) was not significantly (p > 0.05) affected by the interaction effect of tillage and nutrient on the surface soil layer (0–5 cm). Interaction effect of tillage and nutrient was significant on available P content at 5–15 cm soil depth. In contrast to N, soil available P relatively increased with reversal of tillage in both NT and RT. Tillage reversal (NT-CT, RT-CT) and RT had significantly higher available potassium than NT in 0–5 and 5–15 cm soil layers. Among the treatments, NT-CT-T3 showed significantly higher seed N (85.49 kg/ha), P (10.05 kg/ha), and K (24.51 kg/ha) uptake in soybean. The study indicates conventional tillage with residue returns and integrated nutrient management could be a feasible alternative to overcome the limitations of no-till farming in the deep black Vertisols of Central India.

“…However, Tony and Janovick [129] reported that long-term minimum tillage required higher amount of K application to maintain K supplying capacity in subsurface layer, because of its immobile nature together with its accumulation in the surface layer. When soil is rich in K or adequate amounts of K fertilizer were previously applied to the calcareous soils, extractable K was not affected by disturbance of soil (tillage) and residue management [130].…”

Rice (Oryza sativa L.) Establishment Techniques and Their Implications for Soil Properties, Global Warming Potential Mitigation and Crop Yields

et al. 2020

Rice-based intensive cropping systems require high input levels making them less profitable and vulnerable to the reduced availability of labor and water in Asia. With continuous conventional puddled rice transplanting, the situation is exacerbated by damaged soil structure, declining underground water and decreasing land and water productivity. To minimize these negative effects a range of new crop establishment practices have been developed (zero tillage, dry direct seeding, wet direct seeding, water seeding, strip planting, bed planting, non-puddled transplanting of rice, mechanical transplanting of rice crop and combinations thereof) with varying effects on soil health, crop productivity, resource saving and global warming mitigation potential. Some of these allow Conservation Agriculture (CA) to be practiced in the rice-based mono-, double- and triple cropping systems. Innovations in machinery especially for smallholder farms have supported the adoption of the new establishment techniques. Non-puddling establishment of rice together with increased crop residue retention increased soil organic carbon by 79% and total N (TN) in soil by 62% relative to conventional puddling practice. Rice establishment methods (direct seeding of rice, system of rice intensification and non-puddled transplanting of rice) improve soil health by improving the physical (reduced bulk density, increased porosity, available water content), chemical (increased phosphorus, potassium and sulphur in their available forms) and biological properties (microbiome structure, microbial biomass C and N) of the soil. Even in the first year of its practice, the non-puddled transplanting method of rice establishment and CA practices for other crops increase the productivity of the rice-based cropping systems. Estimates suggest global warming potential (GWP) (the overall net effect) can be reduced by a quarter by replacing conventional puddling of rice by direct-seeded rice in the Indo-Gangetic Plains for the rice-based cropping system. Moreover, non-puddled transplanting of rice saves 35% of the net life cycle greenhouse gases (GHGs) compared with the conventional practice by a combination of decreasing greenhouse gases emissions from soil and increasing soil organic carbon (SOC). Though the system of rice intensification decreases net GHG emission, the practice releases 1.5 times greater N2O due to the increased soil aeration. There is no single rice establishment technology that is superior to others in all circumstances, rather a range of effective technologies that can be applied to different agro-climates, demography and farm typologies.

Soil chemical properties play important roles to support plant growth. It determines the nutrient availability which is required by the plant. This study aimed to identify the influence of soil chemical properties on cajuput stand growth. It was conducted in Forest Resort Gubugrubuh, Gunungkidul District. Data collection was undertaken in 3 sites that became the priority sites of cajuput establishment, namely site 75, site 78, and site 80. It was divided into soil sample collection and cajuput stand measurement. The soil sample was collected from surface layer at depth of 0-15 cm. Afterward, it was tested in the laboratory for soil pH, soil organic carbon, total nitrogen, available phosphorus, total potassium, and cation exchange capacity (CEC). The measurement of cajuput stand was carried out by N-trees sampling. The variable of the stand was described by diameter and basal area. Comparison of soil chemical properties and cajuput stand growth from each site were analyzed using One Way ANOVA (α=0.05) followed by HSD Tukey (α=0.05). Furthermore, we used Stepwise Regression (α=0.05) to identify the influence of soil chemical properties on cajuput stand growth. The results showed that total nitrogen was the only soil chemical parameter that was significantly different between sites (p<0.05). However, the growth of cajuput stands was not significantly different between sites (p<0.05). This study found that available phosphorus and cation exchange capacity had clearly influenced on diameter and basal area.
