b'PhosphatePhosphate has a stimulating and positive effect on root growth. Especially immediately after planting, the need is great and a large part of the phosphate is absorbed, which is only needed later in the season. A good root system also ensures good development of the above-ground plant parts.Phosphate is part of a molecule that provides energy transport within the plant. By light on the plant, energy is stored and transported to the chlorophyl grains in the leaf. This energy is released again to make sugars. These sugars are used in the plant for all kinds of processes such as respiration and growth. Phosphate plays an important role in this.Bound phosphate can dissolve through acids produced by the root. Part of the bound phosphate can eventually dissolve because it is less strongly bound to organic parts, for example. The majority of the phosphate stock in the soil is strongly bound to iron, calcium or aluminium and is therefore not absorbable by the plant.Phosphate absorption takes place actively and is therefore temperature dependent. Because phosphate is difficult to move in the soil, the importance of a well-developed root system is crucial for good absorption. When the soil pH is between 5.0 and 6.0, most of the phosphate is available to the plant. A pH of more than 6.0 or less than 5.0 ensures that there is less absorbable phosphate for the plant.Deficiency symptomsIf the soil temperature is too low and the weather is sunny, especially in spring, it can easily lead to a phosphate deficiency. This is reflected in the older leaves in a darker coloured leaf which has a coarse purple / red colour at the edges. Root growth is much less and fruit abnormalities 110'
