Move from general product information to a clear, crop-specific programme — from nursery preparation to field application.
Guidance supplied by Ken & Tech in September 2026. Where rates are unconfirmed, request an approved programme before application.
Sow directly. Place 10 kg/acre (about 25 kg/ha) near the seed row at planting without concentrating it against the seed. Blend with basal fertiliser, mature manure or compost for even placement; the maize protocol suggests 1 part Maxyield to 5 parts fertiliser. Apply a further 10 kg/acre during the normal top-dressing operation, preferably before rain or irrigation. Total: 20 kg/acre per crop.
Higher doses at very low pH require technical approval and a soil test; they are not included in this calculator.
pH is a guide, not a yield prediction. These ranges need local soil-test interpretation; unlisted values are not automatically safe.
Best pH conditions for this crop; no yield percentage is promised.
Usually a lower pH risk; test nutrients and monitor the crop.
Increasing risk of reduced growth or yield; investigate soil acidity and nutrition.
Higher risk of root or nutrient limitations; seek a soil-test-based correction plan.
Check for nutrient limitations, particularly micronutrients.
Maxyield is a soil conditioner. It does not replace fertiliser or a soil-test-based liming programme. Nursery media rates are separate from field rates.

10 kg/acre at transplanting and 10 kg/acre at first top dressing during active growth / tillering. Nursery preparation and later side dressings for extended or ratoon crops are separate from this field estimate.
10 kg/acre at transplanting and first top dressing (35–45 days later). Long-season crops: separate repeat applications every 2–3 months where required. Nursery preparation is excluded from field estimates.
Nursery preparation, planting and top dressing.
Nursery preparation, planting and top dressing.
20 kg/acre at transplanting and 20 kg/acre at top dressing 6–8 weeks later: 40 kg/acre (100 kg/ha) per season. Nursery preparation is separate; no automatic pH-based increases.
Standard programme: 80 kg/acre at planting and 80 kg/acre at top dressing. Optional nursery preparation is separate; low-pH adjustments require agronomic review.
10 kg/ha at planting and 10 kg/ha at top dressing; 20 kg/ha per crop cycle. The calculator uses hectare-based rates from this version.
Dated version covering nursery, new plantings, established fields and split applications.
Farm-specific programme for 17.5 hectares. Its farm totals are not a general order recommendation.
Proposed nursery trial for Brown Plantations. Experimental design remains to be completed; quantities are based on growing-media weight, not field area.
