Kedah’s rice bowl (Kota Setar, Pendang, Yan, Kubang Pasu, Pokok Sena) is farmed intensively on heavy clay, much of it double-cropped within the MADA irrigation scheme. Intensive cropping draws down soil organic matter — a soil test shows where your field stands.
Kedah is the country’s main rice-growing state, with much of the area within the Muda Agricultural Development Authority (MADA) irrigation scheme. Decades of double cropping on heavy clay, together with heavy machinery, can reduce organic matter and compact the soil below the plough layer.
NEXGROW is a bio-organic fertiliser, processed in line with MS 1517:2012, that adds organic matter and phosphate-solubilising bacteria. The NEXGROW booklet sets the paddy rate by soil cation exchange capacity (CEC): 400 kg/ha where CEC is above 20, 1–2 t/ha at 10–20, and 3–5 t/ha below 10 cmol(+)/kg. That is why we start with a soil test.
NEXGROW goes in as the basal round; your normal top-dressing programme continues. Rates come from the booklet and your soil test.
Cation exchange capacity decides the NEXGROW rate for paddy — from 400 kg/ha up to 3–5 t/ha on low-CEC soil.
Aerobically processed organic matter supports soil structure in heavily worked clay.
Phosphate-solubilising bacteria help convert bound soil phosphorus into plant-available forms.
