Abstract Accurate phosphorus (P) fertilizer recommendations for soybean [ Glycine max (L.) Merr.] and corn ( Zea mays L.) are crucial maximizing productivity economic return while minimizing the environmental impact of use. Currently, there no calibrations diagnosing P deficiencies in croplands Bolivia. This study aimed to define compare critical soil test value (CSTV) using Olsen method. Twenty fertilization field trials were conducted 75 Santa Cruz de la Sierra region, including treatments...
Core Ideas Traditional corn N diagnostic methods (pre‐plant nitrate test and pre‐sidedress test) only account for mineral N. Objective: to improve by considering mineralization. Pre‐plant were improved anaerobic‐N (N an ) in areas with similar soil/climates. Models combining , texture temperature pre‐plant all areas. Current ( Zea mays L.) are often based on the nitrogen (NO 3 − –N) concentration before planting test, PPNT) at V6 stage (PSNT). These tests provide scant information soil...
Abstract Management practices, such as tillage and cropping diversification, influence soil phosphorus (P) dynamics. The aim was to evaluate the long‐term effect of systems (no tillage, NT; vertical VT; conventional CT) on total (TP) extractable (Pe) P distribution under different crop sequences (corn–wheat/soybean, C–W/S; wheat/soybean, W/S; corn–corn, C–C; soybean–soybean, S–S). TP Pe were measured up 50 cm deep. associated organic carbon (SOC) ( r = .89, p < .01) tend increase near...

The nitrogen (N) released after 7‐d anaerobic incubation is good estimator of the size soil mineralizable pool. However, there lack information on how properties climate affect apparent this objective our study develop validate simple estimate corn ( Zea mays L.)...
<title>Abstract</title> The global food system relies on crop production in limited number of regions around the world. South American Pampas region is a major breadbasket due to favorable weather and fertile soils for reliable capacity produce large grain oilseeds surplus. However, decades, nutrient inputs have been much lower than other regions, leading heavy “mining” soil stocks. Here we evaluated impact degradation using surveys field-level data sets from across Pampas. Compared balanced...

Poultry litter (PL) is widely used as an alternative to inorganic fertilizers (IF) in conventional (CT) no‐tillage (NT).

Abstract Nitrogen (N) deficiency could have a negative effect on sunflower ( Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, frequency of N fertilization improve crop nutrition. Our objective was evaluate splitting yield, oil Twelve field experiments were carried out between 2016 2020. Treatments consisted at least three rates ranging from 0 200 kg ha −1 applied V 2 . Moreover, 80 rate 14 (80N V14 ) or split ). evaluated in two...
Phosphorus in the soil particulate fraction (PF, >53 µm) has been described to have a significant importance P cycling. However, there is no information regarding effect of management practices over P–PF and its association with organic carbon (SOC) dynamics. Changes total phosphorus (Pt), inorganic (Pi), (Po), Bray-P, SOC through time were evaluated whole soil, PF associated (AF, <53 µm). Two different tillage systems: conventional (CT) no-till (NT), two fertilization treatments: N (no...
Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, timing, placement techniques. This study aimed evaluate whether different Zn-AS (soil, seed, foliar) affect maize GY concentration in Mollisols with contrasting soil availability pH. Five site-years field experiments were carried out. Treatments (Zn-AS) compared a control,...
Core Ideas Critical S dilution curve was established for maize: concentration = 2.13 × biomass −0.23 . The nutrition index successfully diagnosed status at early crop stages (∼V 6 ). Sulfur and chlorophyll meter reading, both in the upper leaf, were good predictors of index. (S) deficiency can severely limit maize ( Zea mays L.) yield. This could be predicted by quantifying (S C ) shoot (BM) calculating (SNI observed /critical However, as determination is laborious, alternative diagnostic...
Soil health status should be monitored to allow planning sustainable management, but indicators available do not encourage frequent soil evaluation because of the complexity, time-consumption, and expensiveness methodologies. Aggregate stability (AS) is a good physical indicator associated with (SOC) particulate (POC) organic carbon difficult monitor. Anaerobically mineralizable nitrogen (AN) has been proposed as cheap, simple, safe measure, sensitive soil-use changes, also related carbon,...
