Oil palm plantations are intensively managed agricultural systems that increasingly dominate certain tropical regions. monocultures have been criticized because of their reduced biodiversity compared to the forests they historically replaced, and negative impact on soils, water, climate. We experimentally test whether less intensive management schemes may enhance lessen detrimental effects environment while maintaining high yields. compare versus conventional fertilization, as well...
Abstract Oil palm is the most productive oil crop, but its high productivity associated with conventional management (that is, fertilization rates and herbicide application), causing deleterious environmental impacts. Using a 2 factorial experiment, we assessed effects of vs reduced (equal to nutrients removed by fruit harvest) mechanical weeding on ecosystem functions, biodiversity profitability. Analysing across multiple exhibited higher multifunctionality than treatment, although this...
The expansion of the oil palm industry in Indonesia has improved livelihoods rural communities, but comes at cost biodiversity and ecosystem degradation. Here, we investigated ways to balance ecological economic outcomes cultivation. We compared a wide range production systems, including smallholder plantations, industrialized company estates, estates with agronomic management, native tree enrichment. Across all management types, assessed multiple indicators biodiversity, functions,...
Abstract Intensive management practices in large-scale oil palm plantations can slow down nutrient cycling and alter other soil functions. Thus, there is a need to reduce intensity without sacrificing productivity. The aim of our study was investigate the effect on gross rates N fertility. In Jambi province, Indonesia, we established experiment plantation compare conventional (i.e. high fertilization herbicide weeding) with reduced mechanical weeding). Also, compared typical zones...
Abstract. Nutrient leaching in intensively managed oil palm plantations can diminish soil fertility and water quality. There is a need to reduce this environmental footprint without sacrificing yield. In large-scale plantation Acrisol soil, we quantified nutrient using full factorial experiment with two fertilization rates (260 kg N, 50 P, 220 K ha−1 yr−1 as conventional practice 136 17 187 yr−1, equal harvest export, reduced management) weeding methods (conventional herbicide application...
Abstract. Nutrient leaching in intensively managed oil palm plantations can diminish soil fertility and water quality. There is a need to reduce this environmental footprint without sacrificing yield. We quantified nutrient large-scale plantation on Acrisol with factorial treatment combinations of two fertilization rates (260 N, 50 P, 220 K kg ha−1 yr−1 as conventional practice, 136 17 187 yr−1, equal harvest export, reduced management) weeding methods (conventional herbicide, mechanical...
A sustainable management of highly productive eucalypt plantations requires the application fertilizers to balance nutrient exports associated with biomass removal every 6-7 years. Although deep leaching after clear-cutting is an important component input-output budgets nutrients in forest soils, accurate quantifications are rare tropical plantations. Our study aimed assess consequences practices on losses by comparing two Ferralsols contrasting clay contents (40% vs 20% clay) same...
