Phosphorus and Potassium Deficiency in Plants Solved

Plant Nutrition Deficiencies:Phosporus and Potassium We have talked bout the role nitrogen played in played health and what to look for if a plant was deficient in one of the major nutrients, being Nitrogen. <ul><li>In fact there are three major nutrients which are classified as NPK ratio on the back of all fertilisers. So in this part of the blog, we carry on with the two other major or macro nutrients.</li> </ul> Let's look at phosphorus deficiency Phosphorus is responsible for the development of flowers and fruits and roots. <ul><li>Phosporus is known as a mobile nutrient which can move around the plant to where it's needed.</li> <li>Phosphorus deficiency happens more often in cold weather or gardens receive high rainfall, or a combination of both.</li> <li>Often affects heavily fruiting plants such as citrus.</li> <li>N..B. native plants are highly sensitive to phosphorus, so avoid spreading phosphate fertilisers near these plants. <a href='https://blogger.googleusercontent.com/img/a/AVvXsEhbvN_NQqp81-4aaqF_VaDot81C49PuHZhksmJTjgFzSNxXzGmtlXBUUSzZ5xQwZqb7nmnf6i9PDNEElD58eNmFAacMQ-x04py3NANCBNNJEjDiczjLNQsz3AXpG3q_23oXS088QqkulOHAb9lqlJIWVCHhQ3rUK3VZWk83M6D7kg36ErdesHL9yOgKCA=s1920'></a> </li> </ul> First Symptoms: Older leaves become quite a dark green then develop a purplish tinge.   Tips will then dry off. Not to be confused with lack of watering especially in pot plants where leaves can also develop dry tips. Overall growth is affected in the long term resulting in smaller leaves and stunted growth.   Quick Fix: Fertiliser high in phosphate either solid or liquid. Long term fix: Blood  n' Bone and/or controlled release fertilisers.  Let's look at potassium deficiency Potassium is responsible for thickening of cell walls, and also responsible for plant growth. Potassium deficiency are more evident in flowering or ornamental plants. Potassium deficiency often is a pH issue in the soil. <a href='https://blogger.googleusercontent.com/img/a/AVvXsEi-J1DIqQPAm6PDt9WJDr0Q4TdwvA_XQQK5JN4G7Ts6esg
