Crystalline water-soluble fertilizers, for example, have very low levels of sodium, chlorine, or heavy metals (Table 1). It is intended for use by the fertilizer industry, policy makers and … Inclusion of KCl in the 7-21-7 fertilizer reduced the maximum Solubor solubility, due to the higher salt content of this fertilizer. 0000004936 00000 n If a certain fertilizer is being dissolved in the same solution with another fertilizer that contains a common ion, the solubility of both fertilizers is reduced. Nutrients are expressed on fertilizer labels as nitrogen (N), phosphate (P2O5), and potash (K2O). Water soluble fertilizers (WSFs) Water soluble fertilizers are applied to crops using a number of different application methods but all rely on a high and quick dissolving formulation for application with irrigation water in fertigation, and foliar application, where the fertilizer solution is sprayed onto crop foliage. Solubility of a fertilizer – The solubility of a fertilizer is defined as the maximal amount of the fertilizer that can be completely dissolved in a given amount of distilled water at a given temperature. It is the most widely used potassium fertilizer. !� o�ᵃj�+8k�� 'c���\�7fG�M��ʯ�����o�L��A�a����tNP��[/��Ĉ�*���)��؍M�v`����v0��3��qpN�(!o\��ںʙ�ȶ��-���xM�`�+���i�m��p�toPx����ޔN��W���v�G�Cet��0�&�\�o�d屻�ߋ47�3ΐ���@��ah�nG�1�ק�;P�s�ZiQ�0yg�6�e� ]�F����`�{�yp���Ĉhf.����q��n!X���Mt:O�y$�Ռ�x1+�Ք��D�7«4� endstream endobj 7 0 obj 1298 endobj 17 0 obj << /Type /XObject /Subtype /Image /Name /im1 /Filter /FlateDecode /Width 2443 /Height 209 /BitsPerComponent 8 /ColorSpace [ /Indexed /DeviceRGB 255 16 0 R ] /Length 18 0 R >> stream Nitrogen is by far the largest nutrient, accounting for almost 60% of total consumption. 0 182 0 obj <> endobj The Common Ion Effect - Solubility is also dependent on other fertilizers in the fertilizer solution.

Introduction Under the authorization of the International Fertilizer Association’s (IFA’s) Technical Committee, a working group was formed to address issues dealing with harmonization of fertilizer sampling and analytical methodologies. The solubility of double superphosphate in water is less than one-tenth of that of the other concentrated phosphate fertilizer materials. Potassium sulfate [K 2 SO 4] is known as sulfate of potash and contains 50–53% K 2 O and 17% S. It is used Among the sixteen elements required for the development and growth of any crop, N P K are the major nutrients. 0000003630 00000 n lar fertilizers that are completely water soluble. leaves or fruits of high value crops. It is also the easiest fertilizer to apply for the beginning or the professional gardener and is, therefore, the most widely used. ft. ̶ Slow-release N products, such as sulfur coated urea, are 1½ pounds N per 1,000 sq. 0000041580 00000 n 0000007221 00000 n It is primarily used as a non-pressurized liquid fertilizer and is for many the preferred While synthetic fertilizers are sold primarily on the basis of their water (aqueous) solubility, the emphasis on aqueous solubility is generally misunderstood and somewhat misguided. When applying fertilizers through the irrigation water (fertigation), it is essential to be familiar with some important facts regarding fertilizers solubility.
