Ganoderma basal stem rot in oil palm: how soil ...
Ganoderma basal stem rot reduces oil palm yields by 50 to 80% and worsens with each replanting cycle. Discover how soil biology: Trichoderma, organic matter, and silicon nutrition: forms the...
What happens under the frond stack: the nutrien...
Oil palm frond stacking is universal but rarely managed as a nutrient cycling tool. This article uses decomposition timeline data to show how strategic placement transforms frond biomass into in-situ...
Why your soil organic matter disappears faster ...
At Malaysian temperatures of 28-32 degrees Celsius, labile organic matter decomposes in under a year. This article explains why stabilised humic acid persists where raw compost does not, and what...
Hidden deficiencies in the cacao block: zinc, c...
Zinc is the most frequently deficient micronutrient in cacao globally. In Malaysian acid soils at pH 4-5, both zinc and copper form insoluble precipitates. This article covers diagnosis, foliar correction,...
The nutrient nobody talks about: why sulfur is ...
Sulfur is essential for latex biosynthesis in rubber trees but almost never monitored in Malaysian fertiliser programmes. On leached sandy soils, annual S application is needed to maintain latex quality...
Without the right bacteria, your nitrogen-fixin...
Biological nitrogen fixation in cover crops requires specific Bradyrhizobium strains matched to the species and soil pH. Without inoculation on acid Malaysian soils, the symbiosis fails and the N fixation...
