Agronomy Journal, Volume 118, Issue 3, May/June 2026.Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Relation between multi-nutrient soil tests and boron in barley
Plant, Soil and Environment, 2006 The aim of study was to verify a possibility of adding boron to multi-nutrient soil tests: Mehlich 3, water (1:5) and 0.5M NH4-acetate extraction. Thirty-six different soils from topsoils of agriculturally farmed field were used for the study.

Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems
Agronomy Journal, Volume 118, Issue 3, May/June 2026.Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.

Targeting phosphorus loss with carbon farming practices? Results from an on‐farm study
Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.Abstract Agricultural soils lose P to waterbodies and C to the atmosphere. Reversing the C trend requires change in management (carbon farming), but what is the effect of carbon farming practices on P transport from soils to waterbodies? This was empirically studied by analyzing the P loss risks from 20 farms participating in a 5‐year on‐farm carbon ...

Soil P Status and Nitrogen Fixation on Organic Dairy Farms in Ontario and Nova Scotia [PDF]
, 2010 Legumes are a key source of nitrogen (N) in organic production systems. However, there is evidence that reduced inputs may be leading to deficient soil phosphorus (P) on some organic dairy farms (Roberts et. al. 2008).

Enhancing soil health through no‐till, cover crops, and compost: A 5‐year field study
Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.Abstract The capacity of soil management systems to conserve and promote soil health is crucial for its sustainability. While the effects of individual soil management practices on soil health receive considerable attention, their combined effects remain understudied. This paper presents the results of a 5‐year field experiment designed to evaluate the
