“…The addition of gypsum may increase the availability of Mg and K, leading to potential leaching of these cations into deeper soil depths or loss from the rooting zone (Zoca & Penn, 2017). The increased mobility of Mg due to gypsum application is a result of the formation of mobile Mg-sulfate ion pairs (Hammerschmitt et al, 2021). Both Bossolani et al (2020 and Hammerschmitt et al (2021) found leaching of Mg and K from the rooting zone when lime was combined with gypsum.…”

“…The increased mobility of Mg due to gypsum application is a result of the formation of mobile Mg-sulfate ion pairs (Hammerschmitt et al, 2021). Both Bossolani et al (2020 and Hammerschmitt et al (2021) found leaching of Mg and K from the rooting zone when lime was combined with gypsum. In the treatment involving 2L+1G, which received 0.62 M g ha −1 gypsum, soil exchangeable Mg content increased by 71 mg kg −1 in the 10-to 20-cm depth compared to its pretreatment values, indicating possible leaching of Mg into that depth after 18 months.…”

“…No significant differences (p > 0.05) were observed in exchangeable K content for treatments with gypsum only, or lime and gypsum combinations compared to the control at any depth or sampling date. Bossolani et al (2020) and Hammerschmitt et al (2021), who both observed leaching of K with lime plus gypsum combinations, conducted long-term studies (+17 years) in regions with average rainfall of 1360 and 1416 mm year −1 , respectively. Whereas in the Swartland region, where this trial took place, the average rainfall is 392 mm year −1 .…”

“…Soils affected by subsurface acidity and metal toxicity result in depth‐limited root penetration and proliferation, leading to restricted water and nutrient uptake by the roots (Zoca & Penn, 2017). The presence of soil acidity and metal toxicities poses a significant challenge in dryland crop production systems with limited water availability (Hammerschmitt et al., 2021). In regions with Mediterranean climates, such as the one studied here, terminal drought plays a crucial role in determining crop productivity.…”

“…In Western Australia's Mediterranean climate regions, soil acidity has been shown to reduce average grain yields by up to 60% (Tang et al., 2003). While deep lime placement followed by incorporation has proven effective in alleviating subsurface acidity, it is not economically viable (Azam & Gazey, 2021; Hammerschmitt et al., 2021; Tang et al., 2012). An alternative proposed strategy is the combined surface application of lime and gypsum, which has shown to enhance downward movement of alkalis and alleviate Al toxicity more effectively than sole surface lime application on highly weathered acid soils (Anderson et al., 2020; Carmeis Filho et al., 2017; Farina et al., 2000a; Zoca & Penn, 2017).…”

Some no‐tillage systems necessitate amelioration of subsurface acidity. A two‐year field trial was conducted on a no‐tillage sandy loam Cambisol, with a pH(KCl) of 4.20 in the 10 – 30 cm depth. The aim was to evaluate one‐time tillage, calcitic lime forms and lime plus gypsum combinations on soil chemical parameters, wheat (Triticum aestivum L.) and canola (Brassica napus) production. Incorporation of lime (1.67 Mg ha−1) through one‐time chisel ploughing increased soil pH(KCl) and soil exchangeable calcium in the 20 – 30 cm depth by 9.1 and 210.1%, respectively, after 18 months. Conventional one‐time tillage treatments resulted in 15.0 – 18.1% reduced wheat seedling establishment in the subsequent season. Surface‐applied hydrated lime (1.56 Mg ha−1) and micro‐fine pelletized lime (1.75 Mg ha−1) both caused over‐liming (pH(KCl) > 6.5) effects in the 0 – 5 cm depth after 6 months, which attenuated from 12 to 18 months. Surface‐applied lime (1.67 Mg ha−1) showed a 2.9 and 5.6% pH(KCl) reduction in the 10 – 20 and 20 – 30 cm depths, respectively, after 18 months. While combined surface application of lime (0.55 Mg ha−1) plus gypsum (1.25 Mg ha−1) showed a 3.7 and 0.5% pH(KCl) reduction in the 10 – 20 and 20 – 30 cm depths, respectively, after 18 months. Wheat (year 1) and canola (year 2) yield and seed quality parameters were unaffected (p > 0.05) by the treatments. Subsurface acidity amelioration in no‐tillage systems is best achieved through chisel lime incorporation or combined surface application of lime plus gypsum on moderately or highly weathered soils.This article is protected by copyright.

Proper soil sampling is critical for accurate fertilizer recommendations. Samples collected in extremely wet or dry conditions may compromise the integrity of the sample and influence analytical results. We evaluated the effects of six soil moistures, two sampling depths (0–10 and 0–15 cm), and two soil probes on soil core uniformity and soil test results. Moisture treatments encompassed a range from dry (11.2%–18.5% moisture) to saturated conditions in Captina, Dewitt, Calhoun, and Calloway silt loam soils. Core depth and dry core weight were measured in all soils, and pH and Mehlich‐3 extractable P, K, S, and Zn were assessed for Calhoun and Calloway soils. Soil moisture, probe, or their interaction influenced core depth and weight, while chemical properties were significantly affected only by soil moisture. Sampling very dry or saturated soils compromised the collection of uniform cores mainly for the 0‐ to 15‐cm depth. Soil pH tended to increase with increasing moisture, but the mean values fluctuated only ±0.3 units. Across soils and depths, extractable S consistently decreased by 16%–48% as soil moisture at sampling time increased. Phosphorus was affected by soil moisture for 0–15 cm samples in both soils but showed no clear pattern. Soil moisture at the time of sampling affected soil test K for both soils and sample depths with individual cores varying up to 47 mg kg−1 (i.e., 59–106 mg kg−1). Greater soil test P and K variability occurred for very dry and wet conditions, which often prohibit collecting samples to the proper depth and could impact fertilizer rate recommendations.
