Nitrogen cycling in coffee plantations

Plant and Soil, 1982
Nitrogen inputs to the coffee ecosystem are dominated by additions of fertilizer-N (100–300kg N ha-1 yr-1). Small nitrogen inputs from rains and variable from inputs fixation by the leguminous shade trees can amount to 1–40 kg N ha-1 yr-1. Organic matter mineralization can be an important nitrogen source also.

Shade management in coffee and cacao plantations

Agroforestry Systems, 1997
Shade trees reduce the stress of coffee (Coffea spp.) and cacao (Theobroma cacao) by ameliorating adverse climatic conditions and nutritional imbalances, but they may also compete for growth resources. For example, shade trees buffer high and low temperature extremes by as much as 5 °C and can produce up to 14 Mg ha−1 yr−1 of litterfall and pruning ...
