Castor meal is also variously called castor meal, castor residue, castor extract & de-oiled castor cake Castor meal - the residue obtained from castor cake by the solvent extraction process - is one of the most versatile natural manures. It is truly organic manure which enhances the fertility of the soil without causing any damage or decay. It is enriched with the three big elements vital and conducive to the proper growth of crops - Nitrogen, Phosphorus and Potassium. It also has traces of nutrients like Manganese, Zinc and Copper, thus making it a balanced fertilizer. Moreover, it helps to neutralize the detrimental effects of chemical fertilizers. Apart from their contribution to Nutrients, they have a number of benefits in agriculture, which none of the synthetic fertilizers or pesticides can offer. They bring in the wonderful molecules that nature has designed to help the plants flourish naturally. They provide slow and steady nourishment, stimulation, protection from soil nematodes and insects; improve yields, and quality of product like taste, flavour, amino acid composition etc. The pressed cake obtained after the expression of castor bean. The solvent extracted cake, although rich in protein cannot be used as cattle fodder because of its toxicity. However, it can be used as a fertilizer. The protein content of castor seed meal varies from 21-48% depending upon the extent of decortications. It has an ideal amino acid profile with moderately high Cystine, mithionine, and isoleucine. But its ant nutritional substances, ricin, ricine and an allergen restrict its use in poultry feed, even at a very low level of inclusion. Castor Cake is an excellent fertilizer because of high content of N (6.4%), Phosphoric Acid (2.55%) and Potash (1%) and moisture retention. There is negative correlation between the contents of ricinine in castor seeds and oil content (r = -0.76). This content of ricinine in castor seed is determined by Agro climatic conditions. Nutrient content of Castor Cake: Organic matter - 75 - 80 %, Nitrogen - 4.0 - 4.5 %, Phosphorous - 1.5 %, Potassium - 1.25 - 1.5 %. It also contains some micro nutrients viz., Calcium, Magnesium, Sulphur, Iron, Zinc, Manganese, Copper etc. A typical composition of castor residue/meal is as follows: Nitrogen - 4% min. approx. Phosphorous - 1% min. approx. Potassium - 1% min. approx. Moisture - 10 - 12 % max. approx. Oil Content - 0.7% max. approx. Advantages: 1. It provides all the major & minor nutrients necessary for better plant growth. 2. It also helps in increasing the nutrient uptake by plants. 3. It improves the soil fertility and productivity. 4. It is known to protect the plants from nematodes and termites. 5. It improves the yield & quality of the farm produce. 6. It improves the physical, chemical and biological properties of soil

However, the product turns red when it encounters metal ions, so other components such as formula water should not introduce metal ions. The equipment should be made of pure stainless steel, and an appropriate amount of EDTA-2Na should be added to the formula water phase to chelate with metal ions.
Kiwi : The world's largest consumption of the first 26 kinds of fruit, kiwi is the most comprehensive. The content of Vc, Mg and trace elements in kiwifruit fruit was the highest. Among the top three low-sodium and high-potassium fruits, kiwi is at the top of the list because it contains more potassium than bananas and citrus. At the same time, the content of Ve and Vk in kiwifruit was determined to be excellent, low in fat and no cholesterol. According to the analysis, kiwi fruit vitamin content per 100 grams of fresh samples in general 100-200 mg, high up to 400 mg, about 5-10 times the citrus; sugar 8-14%, acid 1.4-2- 0%, but also with tyrosine and other amino acids 12 species. kiwi fruit contains a wide range of nutrients, most of the fruit is rich in one or two nutrients, but each kiwi can provide 8% DV folic acid, 8% DV copper, 8% pantothenic acid, 6% Fresh, 4% DV iron and vitamin B6, 2% DV phosphorus and Va as well as other vitamins and minerals. Kiwi in addition to kiwi alkali, proteolytic enzymes, tannin pectin and sugar and other organic matter, as well as calcium, potassium, selenium, zinc, germanium and other trace elements and the human body needs 17 kinds of amino acids, but also rich in vitamins, , Fructose, citric acid, malic acid, fat. A kiwi can provide a day more than twice the demand for vitamin C, known as the "king of fruit." Kiwi also contains good soluble dietary fiber, as the fruit of the most eye-catching place is contained in its superior antioxidant properties of plant chemical substances sod, according to the US Department of Agriculture research report, kiwi comprehensive antioxidant index in the Fruits among the top, second only to the thorns, blueberries and other small fruit, far stronger than apples, pears, watermelon, citrus and other daily fruits. And blueberries belong to the second generation of fruit is quite representative. Compared with sweet orange and lemon, kiwi fruit contains vitamin C ingredients are two times the first two fruits, so often used to fight against scurvy. Not only that, kiwi can stabilize mood, lower cholesterol, help digestion, prevent constipation, as well as thirst and diuretic and protect the role of the heart.
