P l a n t N u t r i t i o n Foliar Feeding Of Nutrients Foliar application of plant nutrients can produce higher yields and make your nutrition program more efficient. By Charlie O’Dell FOR many years, horticulturists and agronomists have largely subscribed to the belief that foliar feeding of plant nutrients is an idea of dubious merit best employed only where a specific minor element deficiency may exist. Dramatic and fast correction of such nutrient deficiencies are almost always seen from such foliar applications. Dr. H.B. Tukey, renowned plant researcher and head of the Michigan State University (MSU) Department of Horticulture in the 1950s, working with research colleague S.H. Wittwer at MSU, first proved conclusively that foliar feeding of plant nutrients really works. Researching possible peaceful uses of atomic energy in agriculture, Permberian baja secara foliar telah terbukti dapat meningkatkan hasil dan menjadikan sistem pembajaan lebih cekap. Kaedah pemberian baja forliar telah terbukti berkesan oleh Dr. H.B. Tukey dari Michigan State University pada tahun 1950 han lagi. Ahli2 agronomi dan hortikultur telah mengesahkan pemberian secara foliar ialah sangat berkesan terutama sekai bagi merawat tanaman yang menunjukkan kekurangan nutrien tertentu. Berdasarkan kepada maklumat ini, tenaga atomic mungkin boleh dimenafaatkan dalam pengeluaran tanaman pada masa hadapan. “Comparing efficiency of plant use of foliar-fed nutrients versus soil-applied nutrients near roots, they found foliar feeding provided about 95% efficiency of use compared to about 10% of use from soil applications.” Likewise, speed of absorption and use by foliar applications was immediate, Kecekapan pengambilan oleh tanaman. Kecekapan pengambilan zat nutrien bagi pemberian baja secara foliar adalah 95% berbanding dengan hanya 10% bagi pemberian baja secara aplikasi tanah. Disamping itu, pengambilan zat nutrien oleh tanaman bagi pemberian baja secata foliar adalah serta merta. it is important to bring these science-based findings to light and publicize this work to benefit growers and their crops commercial agricultural chemists began developing foliar feeding formulations ~ Formulasi baru baja foliar Penemuan Saintifik yang penting seperti ini seharusnya disebar luas demi kepentingan semua semua petani dan tanaman mereka Pada masa ini ahli kimia komersial sedang membangunkan formulasi baja foliar yang bersesuaian dan cekap untuk kegunaan petani berkenaan whereas from soil applications absorption and plant use both were very slow, thus providing a major benefit of foliar feeding where a specific plant nutrient deficiency may exist, be it a major or minor nutrient. You’ll note from references of these researchers’ work cited herein that this very important finding was published, but only in research journals and symposia proceedings. These findings rarely made their way into the ranks of Extension educators or their grower-focused publications and other teaching materials or programs. Now, a half-century later, it is important to bring these science-based findings to light and publicize this work to benefit growers and their crops. Putting It To Good Use Armed with this knowledge dug from research journals, commercial agricultural chemists began developing foliar feeding formulations Maklumat R&D Pemberian secara aplikasi tanah pada umumnya lambat untuk mendapat kesan rawatan terutama sekali dalam keadaan kekurangan nutrien tertentu dikesan (sama ada zat nutiren makro atau mikro). Kebanyakkan keputusan kajian saintifik seperti ini telah diterbitkan dalam jurnal penyelidikan, konferen dan simposim sahaja. Maklumat ini walau bagaimanapun tidak banyak diterbitkan dalam penerbitan pengembangan pertanian dan memaklumkan kepada petani tentang penemuan2 ini.
