“…According to Zibilske and Bradford [33] and Williams et al [34], zone tillage, e.g., strip-till or ridge tillage, enhances the retention and accumulation of water in topsoil. This is due to the improvement of many physical and chemical properties of soil, e.g., the accumulation of organic matter, the formation of permanent soil structure aggregates [35,36]. In the present research, a higher water content in soil, both in autumn and spring-summer winter wheat vegetation, was found for ST technology.…”

Zonal tillage, including strip-till, can have a positive effect on soil properties, seed germination, plant emergence, growth, and yield of crops. The aim of this two-factor field experiment was to compare different technologies of basic soil tillage, fertilisation, and sowing of winter wheat carried out after two post-harvest agrotechnical practises in a region with low rainfall. The three treatments of the first factor were: conventional technology (CT)—plough tillage, pre-sowing fertilisation, seedbed preparation and sowing; reduced technology (RT)—plough tillage replaced with deep loosening and (ST)—one pass strip-till technology using a hybrid machine. Agrotechnical practises carried out after the harvest of the previous crop were the second factor treatments, i.e., crushed straw and shallow tillage (TS), mulch from crushed straw (MS). The measurement of the treatment effects included changes in soil moisture, plant emergence, yield components and their correlation, grain yield, and the dependence of the yield components on soil moisture. Wheat growing in ST technology resulted in a higher soil moisture than in RT and CT. Only immediately after winter was the soil moisture similar. Grain yield in ST was similar as in CT and significantly, up to 10.4%, higher than in RT. The higher ST grain yield resulted from uniform plant emergence, greater ear density, and grain weight per ear. The correlation between yield components was weaker in ST than in CT and RT. The positive dependence of the size of the crop components on soil moisture was also weaker. The agrotechnical practises performed right after the previous crop harvest affected neither the soil moisture during the growing season of winter wheat, nor the grain yield and its components.

“…The yield reduction in no‐till relative to strip‐till in our study is possibly due to the cooler and wetter soil conditions from no‐till in early spring, which may contribute to delayed emergence and yield reduction (Buman, Alesii, Hatfield, & Karlen, 2004). Another possible explanation may be attributed to enhanced nutrient uptake, soil organic matter, water use efficiency, water filtration, and water storage capacity with strip‐till relative to no‐till (Fernández & White, 2012; Fernández et al., 2015; Lipiec, Kuś, Słowińska‐Jurkiewicz, & Nosalewicz, 2006; Liu, Zhang, Yang, & Drury, 2013; Messiga et al., 2012; Ziadi et al., 2014).…”

“…Conservation tillage practices like no‐till and strip till have been adopted by many producers to save operational costs, reduce soil erosion, and conserve soil water (Fernández, Sorensen, & Villamil, 2015; Morrison, 2002). The adoption of deep banding of P and K fertilizers for conservation tillage systems has been hypothesized to increase nutrient availability and thus to enhance crop productivity and fertilizer use efficiency (Mallarino & Murrell, 1998; Yin & Vyn, 2002).…”

Soil and crop response to phosphorus and potassium management under conservation tillage

In conservation tillage systems, proper fertilizer phosphorus (P) and potassium (K) management is critical to optimize yield and minimize negative environmental impacts. The objective of this study was to assess the responses of crop yield, nutrient use efficiencies, root growth, and soil test P and K levels to tillage, fertilizer placement, and fertilizer rates in a corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation.Experiments were conducted for 8 yr in Illinois with tillage/fertilizer placement as the main plot (no-till/broadcast [NTBC], strip-till/broadcast [STBC], and strip-till/deep band [STDB]) and PK fertilizer rates as the subplot. The NTBC treatment consistently reduced yields in corn by 6.2 and 4.5% and in soybean by 3.1 and 6.1% relative to STBC and STDB, respectively. Also, NTBC had greater root length density at inrow and between-row positions relative to STBC and STDB. Nutrient use efficiency indices (partial nutrient balance, agronomic efficiency, and partial factor productivity) declined with increasing P and K rates but were not affected by tillage/fertilizer placement treatments. Deep banding significantly reduced soil P and K concentrations in surface layers while increasing them at the depth of application. These results underscore the reported potential for deep banding combined with strip-till to improve conditions for nutrient uptake while reducing the risk for nutrient losses to the environment. Critical soil test P and K levels (21 mg P kg −1 and 217 mg K kg −1 ) were similar for P and greater for K than the current university recommendations, which highlights the need for continuous refinement of soil fertility recommendations to keep pace with changes in production technologies and yield levels.

“…Decisions regarding tillage and fertilization options are expected to be driven by the economics of regional agronomic systems, but these crop cultural practices have the potential to affect soil properties after long‐term cropping. For instance, Fernández et al (2015) showed that improved nutrient uptake efficiency and yields with different tillage systems were partially due to improved soil organic matter, bulk density, and penetration resistance. However, data are limited on the effect of long‐term tillage and N fertilization on claypan soil properties.…”

Core Ideas Claypan soil properties were minimally affected by tillage and N fertilization after 20 years. Soil organic matter distribution was affected by tillage, but with no apparent net difference. Long‐term tillage and N fertilization did not affect soil bulk density or penetration resistance. Subtle long‐term soil changes may not influence producer choices for tillage and N fertilization. Tillage and nitrogen (N) fertilization systems may affect soil chemical and physical properties, especially long term. This study's objective was to examine the effect of three tillage systems (conventional tillage, reduced tillage, and no‐till) with four N fertilizer treatments on properties of a claypan soil in the eastern Great Plains after 20 yr of cropping. Soil chemical and physical properties were little affected by long‐term tillage and N fertilization. The lack of tillage to distribute soil phosphorus (P) and potassium (K) nutrients within no‐till treatments resulted in lower P and K values below the surface. In no‐till, the accumulation of organic matter in the surface soil (0 to 7.5 cm) was countered by lower organic matter in the 7.5‐ to 15 ‐cm zone, resulting in no net increase compared with the other two tillage systems. Soil bulk density and penetration resistance in the surface 30 cm were unaffected by tillage or N fertilization.
