Jackfruit produces the heaviest fruit of any tree crop, and that mass represents a substantial nutrient export with every harvest. Potassium and calcium demand during fruit development is correspondingly high.
It is a long-lived tree, which means soil condition is a multi-decade concern rather than a seasonal one — and root and fruit rot in poorly drained ground is the main threat to a mature stand.
Nangka menghasilkan buah paling berat antara tanaman pokok, dan berat itu mewakili pengeluaran nutrien yang besar setiap tuaian.
Keperluan kalium dan kalsium semasa perkembangan buah adalah tinggi. Saliran yang baik dan kesihatan tanah adalah kunci untuk pokok yang hidup berpuluh tahun.
Very large fruit removes a significant quantity of potassium and calcium from the block with each harvest.
A long-lived tree draws on the same soil for decades, so organic matter decline compounds rather than resets between seasons.
Poorly drained soil drives both root decline and fruit rot, and losses on a mature tree are expensive in absolute terms.
Built to work alongside your existing fertiliser programme, not replace it outright.
Rebuilds organic matter and structure around a long-lived root system, with humic acids improving retention of the potassium and calcium the fruit load demands.
