Plant Nutrients WALT – Explain what else a plant needs to grow WILF – Write the effects on the plants of deficiencies in N, P and K Text book questions 15- 17, pg 17 Scienctifica handout, qs 1-5, pg 57
Non Mineral Nutrients The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon (C). But a farmer cannot control the amount of these nutrients the plants in his field gets
Mineral Nutrients – 2 types Macronutrients – A lot of these are needed Micronutrients – A little of these are needed
Macronutrients – Needed in large amounts nitrogen (N), phosphorus (P), potassium (K). These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival. The secondary nutrients are calcium (Ca), magnesium (Mg), and sulfur (S)
Micronutrients – needed in small amounts boron (B), copper (Cu), iron(Fe), chloride (Cl), manganese (Mn), zinc(Zn). Recycling organic matter such as grass clippings and tree leaves is an excellent way of Replacing nutrients It is not important that you remember these – just interesting !

Deficiency Symptoms of the Macroelements Write the effects on the plants of deficiencies in N, P and K
Nitrogen Deficiency General chlorosis (yellowing) of the leaves. Older leaves showing symptoms first. N deficiency in potato
Phosphorous Deficiency Reduced plant size Darkened foliage with a purplish cast. P deficiency in corn
Potassium Deficiency Margins eventually turning brown. Symptoms develop on lower leaves first. K deficiency on red currant
