Soil and foliar applications of zinc fertilisers can effectively address this problem. But, our knowledge of the cycle of life held within the soil should also be at the forefront of decision-making to ensure a sustainable future.

However most importantly, fertilising with zinc not only increases zinc content in zinc deficient crops, it also increases crop yield.

Balanced crop nutrition by supplying all the essential nutrients, is a recognised, cost effective management strategy. Even with zinc-efficient crop varieties, zinc fertilisers are needed when the available zinc in the topsoil becomes depleted, and we already know that the world’s soil is under serious strain in this regard.

Zinc for Crops

Soil zinc is an essential micronutrient for plant growth and development and is heavily involved in enzyme systems that regulate the early growth stages. It is vital for fruit, seed and root system development, photosynthesis, formation of plant growth regulators and crop stress protection. Zinc is also a team player with nitrogen (N), phosphorus (P) and potassium (K) for many of the plant’s development processes.

Soil however requires zinc in very small amounts compared, for instance, to nitrogen or potassium. Yet, lack of zinc can seriously limit plant growth.
