Targeted Nutrient Placement
Placement of fertilisers at planting allows for effective nutrient uptake such that minerals can be redistributed between different parts of the potato plant to minimise stress and maintain tuber development. Placement of nutrients close to the seed allows more efficient uptake by the growing plant and less opportunity for these nutrients to become fixed into the soil complex.
Such targeted placement can reduce overall fertiliser costs and minimise environmental concerns.
Law’s ‘Potato Plus’
Recent research proves that key trace elements have a role similar to that in humans as antioxidants. Law’s has developed a trace element compound, ‘Potato Plus’, containing specific ratios of calcium, manganese, copper, zinc and sulphur to be incorporated at planting to increase the plant’s ability to counteract environmental stresses.
Recent research shows the correlation between certain trace elements and improved quality characteristics:
- calcium – protects against internal rust spot and improves skin strength and finish
- manganese – reduces common scab and keeps leaves green
- zinc – reduces powdery scab and encourages root growth
- sulphur – improves dry matter formation and is vital for leaf growth
- copper – a catalyst for manganese uptake which increases skin strength
Law’s potato fertiliser system is tailormade for variety, field and market.
