Nutrient critical levels and availability in soils cultivated with peach palm (Bactris gasipaes Kunth.) in Santo Domingo de Los Tsáchilas, Ecuador

Ecuador is the most important exporter of canned peach palm, however, to date ideal soil fertility characteristics for peach palm growers remain unknown. The aim of this research was to determine optimal levels of soil nutrients for the cultivation of peach palm, specifically with regards to soil ca...
