“…Crop production is a normally used gauge for defining ideal N application methods [66]. The results of our study showed that NT, NTN, NTM, and NTNM treatments increased plant height, grain number per spike, 1000-grain weight, biomass, and grain yield to a greater extent than CT, CTN, CTM, and CTNM treatments, which indicated that no-till farming combined with inorganic and organic N fertilizer could increase the yield of wheat, which was consistent with the results of previously published studies [8,67,68]. This may be because no-till did not disturb the soil layer; it maintained the original soil capillary system in the wheat field; the soil bulk density was suitable; and there were more capillary pores, which avoided hardening of the soil caused by overly wet tillage.…”

“…SOC is the main source of many of the nutrients needed by plants and is also the most critical attribute of soil that forms the core of soil quality [8,49]. Our results showed that the total SOC content of the NT, NTN, NTM, and NTNM was higher than CT, CTN, CTM, and CTNM treatments, and SOC decreased with increasing soil depth.…”

“…Nevertheless, N application might lead to soil acidification and deteriorate the soil environment. Consequently, the identification and recommendation of strategies that are both climatesmart and yield satisfactory crop productivity in a recent climate change scenario are significant for crop production in Loess Plateau areas in order to fulfill the up-to-date rise in demand for food and fuel globally [8][9][10].…”

The influence of tillage and nitrogen fertilization methods on soil quality attributes and crop agronomic characteristics has been studied broadly under different agroclimatic conditions. Nevertheless, the interactive effect of tillage and fertilization approaches on soil properties on different soil depths and yield is rarely addressed, particularly on the Loess Plateau belt, and requires more exploration. Thus, this research was conducted in order to evaluate the interactive impact of tillage and nitrogen fertilization methods on soil properties and wheat productivity. The treatments included conventional tillage (CT) and no-till (NT) with different fertilization approaches (no fertilization: CK, chemical nitrogen fertilizer: N, organic fertilizer: M, combined application of nitrogen fertilizer and organic fertilizer: NM) and were explored in a split plot arrangement under a randomized complete block design replicated thrice on soil properties (SWC, SOC, TN, TP, NO3−-N, NH4+-N, and stoichiometric ratio) and wheat yield. The results showed that sole no-tillage and NT in association with nitrogen fertilization (inorganic and organic) significantly increased the soil water content, SOC, TN, NH4+-N, C/P, and N/P ratios and wheat productivity but did not significantly yield TP, whilst it reduced the NO3−-N and C/N ratio compared with sole CT and CT together with nitrogen fertilization (organic and inorganic). Overall, NT in association with the joint application of inorganic and organic N fertilization are the best techniques to improve soil water status and nutrient status under the wheat mono-cropping system conditions and yield.

“…Failure to plow or use various simplified systems leads to the accumulation of SOC, especially in topsoil [ 175 ]. Reduced tillage in comparison with ploughing increased SOC stocks in the surface layer (0–10/15 cm) by 20.8% or 3.8 t ha −1 , depleted SOC stocks in the intermediate soil layers to 50 cm soil depth with a maximum depletion of 6.6% or 1.6 t ha −1 in 15/20–30 cm and increased SOC stocks in the deepest (70–100 cm) soil layer by 14.4% or 2.5 t ha −1 [ 176 ]. However, the use of natural and organic fertilizers is of greater practical importance in maintaining an appropriate SOC [ 177 ].…”

Fertilizer Use Efficiency (FUE) is a measure of the potential of an applied fertilizer to increase its impact on the uptake and utilization of nitrogen (N) present in the soil/plant system. The productivity of N depends on the supply of those nutrients in a well-defined stage of yield formation that are decisive for its uptake and utilization. Traditionally, plant nutritional status is evaluated by using chemical methods. However, nowadays, to correct fertilizer doses, the absorption and reflection of solar radiation is used. Fertilization efficiency can be increased not only by adjusting the fertilizer dose to the plant’s requirements, but also by removing all of the soil factors that constrain nutrient uptake and their transport from soil to root surface. Among them, soil compaction and pH are relatively easy to correct. The goal of new the formulas of N fertilizers is to increase the availability of N by synchronization of its release with the plant demand. The aim of non-nitrogenous fertilizers is to increase the availability of nutrients that control the effectiveness of N present in the soil/plant system. A wide range of actions is required to reduce the amount of N which can pollute ecosystems adjacent to fields.

Organic farming is continuing to expand in Canada, with close to 6,000 producers farming over 2% of all agricultural land. There is insufficient evidence, however, of a trend toward larger average farm size and increasing specialization by these organic farms. This mini-review postulates that a gradient of intensity of farm management exists within organic farming sectors in Canada, with respect to cropping diversity, and tillage and nutrient utilization, and this gradient of intensity is a key determinant of agroecological outcomes. This variation in management approach and intensity reflects producer's individual perspectives on organic farming principles and practices, irrespective of farm scale. By directly influencing farm crop and vegetative diversity and cover, and farm nutrient status and carbon cycling, management intensity determines soil carbon storage and flux, soil health and biodiversity agroecological and ecosystem services, plus farm agronomic resilience. Demographic trends and perspectives of new entrants in organic farming are encouraging signs of an increasingly inclusive and socio-ecologically complex Canadian organic farming sector, which recognizes the agroecological implications of intensity of organic farm management across all production sectors.
