“…A field‐scale investigation covering similar production systems with comparable geographic and climatic conditions also lacked substantive evidence of micronutrient and pH response to practice change in the upper 10 cm of soil, with the exception of Na (Lebeau, 2021). As with the FBM treatment in this study, this result was true for both tilled and reduced till locations.…”

Cover crops have been promoted for increasing soil organic matter, which is critically low in many mid‐Southern US row crop production fields. This study was conducted to inform adaptive management in the early transition period of conservation adoption. Temporal change in soil chemistry was investigated with a split‐field experiment conducted over a 3‐year period in Mississippi corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotational cropping systems that newly implemented winter cover crops and simultaneously reduced tillage. Relative to the untreated (i.e., winter fallow and multiple tillage passes) half of each study field, the chemical soil properties of the treated (i.e., winter cover crop and reduced tillage) half of each study field were not significantly different at the 0.05 significance level. This was true for soil organic matter, all macronutrients, pH, cation exchange capacity, base saturations, and micronutrients, with the exception of iron. Given these results, it is unlikely that growers adopting cover crops while reducing tillage will be able to accumulate significant soil organic matter in the early transition period.

“…As with micronutrients, the field‐scale investigation conducted in neighboring and similar Arkansas lacked substantive evidence of macronutrient response to practice change in the upper 10 cm of soil, with the exception of Na (Lebeau, 2021). Regarding behavior of specific nutrients, p values were consistently lower for CCMT relative to FBM.…”

“…Thus, this study did not take into account the influence of, e.g., cover crops, which may be used by farm entities. In general, cover crops are considered crops that improve soil health by controlling erosion, adding organic matter, and improving water retention capacity [56].…”

This article uses a derived econometric model to estimate the impact of the physical properties of soil on its retention capacity and, subsequently, the impact of retention capacity on production potential. This is an important aspect considering climate change impacts, which are affecting food production across the world. An investigation of academic publications shows that very few studies address opportunities to price rainwater in relation to agricultural production. As such, the objective of the submitted article is to use soil physical property spatial data to create an econometric model. The econometric model itself determines the intensity and direction of action of the soil’s physical properties on the ability of the soil to hold rainwater. The results demonstrate the positive effect of physical properties such as porosity and humus content. Important information for farming practice is the relatively pronounced influence of soil acidity (pH) on its retention capacity, which is mainly the result of its effect on soil biogeochemical processes. The most significant variable in terms of the extent of action is the depth of the soil profile, which is in line with general assumptions. The actual evaluation of soil retention capacity was undertaken using an option with the use of a sensitivity analysis. In order to include the non-production function of the soil (retention capacity), we conclude for individual enhanced quality soil ecological units an increased price of 1–12%. These conclusions are particularly valuable because some soils may have a low production potential while also being highly valuable for their particular location in terms of their non-production potential (typically desirable floodwater retention, etc.). Considering climate change, this is a particularly topical issue. The use of enhanced-quality soil ecological units is reflected in a wide range of fields through legislative processes—determining rural land protection class and, especially in the tax obligations of agricultural entities, farming agricultural land.

Repetitive use of heavy farm machinery in cultivated agriculture may cause soil compaction that can adversely affect soil‐health‐related properties. Cover crops (CC) are well‐documented to alleviate problems associated with compaction and improve overall soil health in time. The objective of this field study was to evaluate the cumulative effects of CC treatment (i.e., with ≥ 6 years cereal rye [Secale cereale L.] CC and ≥ 4 years with no cover crop [NCC]) and sample/measurement placement (i.e., in the bed [B] and in the wheel‐track [WT] and no‐wheel‐track [NWT] furrow) on near‐surface soil physical‐, chemical‐, and infiltration‐related properties in an alluvial soil under cotton (Gossypium hirsutum L.) production in the Lower Mississippi River Valley. Samples were collected and in‐situ measurements were conducted in late May 2019 within a single field in eastern Arkansas. Overall‐infiltration rate was two times greater (p ≤ 0.01) in B compared to WT and NWT placement, which did not differ. Soil bulk density in WT was 1.1 times greater than the other two placements, while soil organic matter was greater in CC‐WT (30.7 Mg ha−1) than in all other treatment‐placement combinations, except for CC‐NWT, which did not differ. Similarly, water‐stable‐aggregate concentration was 2.3 and 1.6 times greater in the CC‐NWT and CC‐WT combinations, respectively, which did not differ, compared to under NCC. Results demonstrated that CC benefits extended beyond the bed to positively affect soil properties in adjacent WT and NWT furrows. Continued small‐scale, long‐term management studies using CC will extend insight into site‐specific, soil‐health improvements.
