• Transfer of Knowledge on Agroforestry Management Practices: the Structure of Farmer Advice Networks (2007, background): “Upper canopy trees are retained or planted to regulate light and they consequently increase farm diversity and enhance biomass inputs, improving soil fertility and plant nutrition (Beer et al. 1997, Hartemink 2005, Isaac et al. 2007).”
• Productivity of Theobroma cacao agroforestry systems with timber or legume service shade trees (2011, background): “…Turrialba, Costa Rica e-mail: esomarri@catie.ac.cr J. Beer e-mail: jbeer@catie.ac.cr nutrients and help to maintain the natural fertility of the site (Hartemink 2005), of utmost importance since most cocoa plantations are not fertilized; and (4) produce goods (wood, firewood, fruits, resins,…”
• Litterfall and litter nutrient dynamics under cocoa ecosystems in lowland humid Ghana (2010, background): “Hartemink (2005) reviewed the results of research on nutrient Mean values in the same column with the same superscript for the different land-uses are not significantly different at P 0.05 level according to Tukey’s HSD test cycling in cocoa ecosystems and found that litterfall production ranged…”
• Effects of an experimental drought on the functioning of a cacao agroforestry system, Sulawesi, Indonesia (2010, background): “…March 2007–February 2008) was within the range (5–21 Mg dry mass ha 1 yr 1; including pruning residues) reported from shaded cacao stands in Malaysia, Venezuela, Costa Rica, Brazil, and Cameroon (Beer, 1988; Hartemink, 2005) and exceeded litterfall of many tropical forests (Vitousek, 1984).”
• Assessing soil fertility decline in the tropics using soil chemical data (2006, background): “It can give insight into the processes that regulate nutrient cycling, and nutrient balances may help to formulate system management decisions and direct the course of research (Hartemink, 2005; Robertson, 1982).”
• Ecological, economic and social perspectives on cocoa production worldwide (2007, background): “pollution due to the generally low levels of fertilizer use among cocoa growers (Hartemink 2005).”
• Shade tree effects in an 8-year-old cocoa agroforestry system: biomass and nutrient diagnosis of Theobroma cacao by vector analysis (2007, background): “As noted in Table 3, the multistrata systems resulted in either a neutral or positive effect on soil exchangeable K pools, probably because of high K inputs from litter and elevated K transfer via rainwash (Boyer 1973; Hartemink 2005).”
