“…Long-term fertilizer application led to a significant decrease in soil pH from an average of 5.3 when no fertilizer was used, to 5.0 at the recommended rate. Similar pH decreases have been observed in other long-term fertilizer application research and were attributed to acidity produced in the nitrification of ammonium to nitrate (Manna et al 2005;Bado et al 2012;Caires et al 2015). The decrease in pH of 0.3 pH units is not large, but in sandy soils such as these with extremely low CEC and OC it may be enough to decrease exchangeable base cations, and increase exchangeable Al ?3 content in the soil solution.…”

Microdosing, the point-source application of a reduced fertilizer rate within 10 days of sowing, has increased short-term crop yields across the Sahel and is being actively scaled up as an agronomic practice. However, there is no information on the longterm effects of the technique upon soil fertility. To rectify this, this study used soil samples from the International Crop Research Institute for the SemiArid Tropics in Sadore, Niger, to assess the effects of 16 years of a reduced fertilizer rate of 15 kg N and 4.4 kg P ha -1 compared to unfertilized soil and a recommended rate of 30 kg N and 13.2 kg P ha -1 upon millet yield trend, soil chemical properties, and soil organic matter quality. The interaction of fertilizer with crop residue and manure amendments at 300, 900, and 2700 kg ha -1 was also assessed. Compared to unfertilized soil, the reduced fertilizer rate improved yield by 116 % but did not increase total N or available P. The recommended rate doubled available P and increased total N by 27 %, but resulted in slightly lower pH compared to the reduced rate. Yield trends were negative for both fertilizer treatments, indicating mineral fertilizer alone is not sustainable at Sadore. Crop residue or manure addition at 2700 kg ha -1 with fertilizer did not improve SOC but buffered pH by 0.3 units, provided nutrients beyond N and P, and changed the forms C and N functional groups in soil organic matter.

“…This suggests a need for adaptation/modifications in NTS to optimize crop performance to achieve food production goals. Generally, the improvement of soil chemical properties under continuous NTS is restricted to a thin top layer, and in acid subsoils of Oxisols, this may compromise water use efficiency and grain yield (Dalla Nora and Amado, 2013;Bortoluzzi et al, 2014;Caires et al, 2015;Zandoná et al, 2015). The surface or low-depth application of fertilizers and amendments (Bortoluzzi et al, 2014), associated with the occurrence of soil compaction and low biological activity, have been identified as main causes for an abrupt chemical quality decline from the surface to subsurface layers of Oxisols under NTS.…”

“…Gypsum (CaSO 4 .2H 2 O) has been recognized as an alternative for improving the chemical quality properties of the root layer under NTS, especially when combined with lime input (Rampim et al, 2011;Watts and Dick, 2014;Caires et al, 2015).…”

Modern maize, wheat, and soybean cultivars are usually characterized by a short cycle, high shoot-root ratio, and high responsiveness to nutrient input. Continuous no-tillage management (NTS) frequently leads to a steep gradient in soil chemical quality with depth, thus decreasing yield under conditions of acid subsoil and water stress. This study aimed to evaluate the effect of gypsum, applied separately or in combination with lime, on the yield of cultivars used in the state of Rio Grande do Sul, Brazil. The study consisted of four experiments conducted on a typic Hapludox under NTS. The experiment was arranged in a randomized block design with three replications. Experiments I and II were carried out on soils with a satisfactory chemical soil quality and tested treatments of gypsum applications ranging from 0.0 to 6.5 Mg ha -1 . The other experiments were carried out on acid soil (experiment III) and a soil with an abrupt drop in chemical quality (experiment IV). Experiment III was arranged in a split plot design, where plots corresponded to gypsum rates between 0.0 and 5.0 Mg ha -1 , and subplots to two lime rates (0.0 and 2.0 Mg ha -1 ). Experiment IV was conducted in a split plot design, with plots consisting of gypsum rates from 0.0 to 6.0 Mg ha -1 and subplots of lime rates from 0.0 to 4.8 Mg ha -1 . Of a set of 17 harvests investigated during the experimental period, 82 % responded with yield increases to gypsum and lime inputs. The gypsum rate that induced the highest grain yield was high (4.7 Mg ha -1 ) and similarly, the maximum technical efficiency of lime was higher than the currently recommended. Furthermore, the combined application of lime and gypsum increased yield. There was a correlation between grain yield with the chemical quality of the soil layer 0.25-0.40 m in experiment I, 0.00-0.40 m in experiment II, and the 0.00-0.25 m in experiment IV. Only in experiment III, where the surface layer was acidic, the diagnostic layer usually sampled (0.00-0.10 m) was correlated with grain yield. Therefore, the use of the 0.00-0.25 m soil layer with critical base saturation values of 65 % and maximum Al saturation of 5 % could improve the current recommendations for soil correction. To exploit the yield potential of modern grain cultivars on dystrophic Oxisol, the formation of a thicker layer with high chemical quality is an efficient strategy.

“…Similares resultados obtuvieron Sikiric et al (2011) con la aplicación de 9 Mg/ha de cal dolomita en un suelo inceptisol, con lo cual aumentó la disponibilidad de Ca y Mg sin que se lograran cambios significativos en los niveles de K. Esto se puede explicar porque que el Mg (y el Ca en menor medida) reemplaza al K en el complejo de cambio (Chatzistathis, Alifragis, & Papaioannou, 2015). No se encontró efecto significativo del encalado sobre el N, el cual, en este suelo, es aportado por la materia orgánica; estos resultados concuerdan con los reportados por Caire, Haliski, Bini, & Scharr (2015), quienes manifestaron que la incorporación de cal en la superficie del suelo no afecta las tasas anuales de nitrógeno.…”

El encalado es una práctica común en el manejo de suelos ácidos, sin embargo, la información sobre encalado en suelos cacaoteros de la Amazonia colombiana es precaria. Se construyeron curvas de incubación en un Typic Udorthents fuertemente ácido cultivado con cacao (Theobroma cacao L., Malvaceae), para lo cual se utilizaron dosis crecientes (0 - 1 - 3 - 5 - 7 - 9 - 11 Mg/ha) de cal dolomita (CaMg(CO3)2) y carbonato de calcio (CaCO3), con el fin de conocer el tipo y cantidad de material encalante (ME) de mejor reactividad y el que más favorece los cambios en la acidez: pH, Al3+, H+ y acidez total. Se construyeron los modelos para estimar la dosis de ME necesaria para llevar el suelo al pH deseado (≥5,5). Posteriormente se encaló el suelo en condiciones de campo y se evaluó el efecto en pH, Al3+, Al en solución (Alsol), saturación de aluminio (SAI), capacidad de intercambio catiónico (CIC) y la disponibilidad de N, P, K, Ca, Mg, Zn, Cu, B, Fe y Mn. Los resultados muestran que la mayor reacción de los materiales encalantes en estos suelos se presenta después de 60 días. Aplicaciones de 7 Mg/ha permitieron elevar el pH de 5,5 a 6,0 y disminuir los niveles de Al y Fe, cambios que mejoraron la CIC y la disponibilidad de nutrientes para cacao (Ca, Mg, P, Zn) sin afectar otros nutrientes como N y K.
