“…It has been reported earlier that the surface soil becomes more acidic under CA practices than that under conventional practice (Limousin and Tessier 2007; Singh et al 2014). The lowering of pH in surface layer under CA-based scenarios has been attributed to build up of soil organic matter and release of organic acids upon decomposition in the surface layer (Singh et al 2014). The EC values in both the soil depths were quite lower than the critical level of 4 dS m −1 in all the scenarios suggesting less chances of salt toxicity in plants on this soil (Table 1).…”

“…Information on soil properties, especially physical properties and nutrient availability under different agricultural management systems is essential for sustainability of the systems (Singh et al 2014). There is an improvement in numerous parameters of soil health (physical, chemical and biological quality) under conservation tillage by increasing carbon and nutrients concentration at the surface soil (Singh et al 2015; Salahin et al 2017).…”

Soil quality degradation associated with resources scarcity is the major concern for the sustainability of conventional rice-wheat system in South Asia. Replacement of conventional management practices with conservation agriculture (CA) is required to improve soil quality. A field experiment was conducted to assess the effect of CA on soil physical (bulk density, penetration resistance, infiltration) and chemical (N, P, K, S, micronutrients) properties after 4 years in North-West India. There were four scenarios (Sc) namely conventional rice-wheat cropping system (Sc1); partial CA-based rice-wheat-mungbean system (RWMS) (Sc2); CA-based RWMS (Sc3); and CA-based maize-wheat-mungbean (Sc4) system. Sc2 (1.52 Mg m−3) showed significantly lower soil bulk density (BD). In Sc3 and Sc4, soil penetration resistance (SPR) was reduced and infiltration was improved compared to Sc1. Soil organic C was significantly higher in Sc4 than Sc1. Available N was 33% and 68% higher at 0–15 cm depth in Sc3 and Sc4, respectively, than Sc1. DTPA extractable Zn and Mn were significantly higher under Sc3 and Sc4 compared to Sc1. Omission study showed 30% saving in N and 50% in K in wheat after four years. Therefore, CA improved soil properties and nutrient availability and have potential to reduce external fertilizer inputs in long run.

“…Studies show that in the longer term, recycling of more crop residues and roots in beds can contribute significantly to the build-up of soil organic matter and availability of nutrients [15], whereas continuous tillage degrades soil organic matter which reduces soil fertility as well as structural stability [16,26].…”

India is the leading country with respect to area and production of pulse crop pigeon pea (Cajanus cajan L.). However, the productivity of this crop is too low and almost static for the last five decades due to cultivation of long-duration cultivars that are prone to climatic variations causing temporary water logging, drought and frost. Proper selection of the cultivar and use of appropriate crop establishment may help in enhancing productivity. Therefore, a field investigation was carried out for 3 consecutive years to determine the impact of establishment techniques on cultivars of two maturity durations-long (250-280 days; cv. JA-4) and short (130-145 days; cv. ICPL-88039), grown using the conventional tillage (CT), minimum tillage (MT), zero tillage (ZT) and broad bed furrow (BBF). The BBF method significantly improved the growth, biological yield, harvest index ratio, water productivity and physicochemical properties compared to the CT, MT and ZT. The yield of pigeon pea seed and stalk under the BBF increased 9.9 and 4.1% compared to the CT. The short-duration cultivar produced higher yield (16.8%) in frost-affected year (2012-2013) but was at par with the long-duration cultivar during the normal climatic condition year (2013)(2014)(2015). Overall, the short-duration cultivar produced significantly higher yield. Land use efficiency and total water use were significantly higher for the long-duration cultivar a compared to the short-duration cultivar, whereas production efficiency and water productivity were higher for the short-duration cultivar. Compared to the other tillage practices, BBF showed significantly higher organic carbon and infiltration rate but decreased pH. The trend of infiltration rate was in the order BBF [ ZT [ MT [ CT. The bulk density of surface (0-15 cm) and sub-surface (15-30 cm) layers were significantly lower under the BBF compared to the other tillage practices. Maximum increment of available N, P, K and S in surface soil (0-15 cm) was recorded under the BBF. For the short-duration maturity cultivar of pigeon pea the BBF method appeared beneficial in terms of assured higher yield, improved water productivity and physicochemical properties of soil under variable climatic conditions in Central India.

“…However, the excessive agricultural traffic, associated with the absence of crop rotation, has led to the formation of compacted layers in the soil under no-tillage system (Franchini et al, 2012). The change of soil structure has led to degradation in several agricultural areas around the world, such as Australia (D'Emden et al, 2006), North America (Munkholm et al, 2013), Europe (López-Garrido et al, 2014), Asia (Singh et al, 2014), and South America (Moraes et al, 2016a).…”

-The objective of this work was to determine whether compaction by tractor traffic in areas managed under controlled traffic can be limiting to corn crop, under different tillage systems, in a Typic Paleudult of medium texture. Two experiments were carried out, one in the field over two crop seasons and another in a greenhouse. The treatments consisted of minimum tillage with chiselling; no-tillage subjected to one, three, or six passes of a tractor weighing 3.8 Mg; and an area without traffic. Evaluations were performed for soil physicohydraulic parameters (soil bulk density, penetration resistance, and water retention curve), root and shoot growth, and grain yield. The agricultural traffic increased bulk density, soil penetration resistance, and water content at field capacity. The highest values for soil penetration resistance (1,600 kPa) and bulk density (1.67 g cm ) in the trafficked soil were not limiting to corn development and increased grain yield for both crop seasons. Tractor traffic of up to six passes is beneficial to corn cultivation, and it increases water availability and corn grain yield.
