Re: No nutritional benefit for organic produce, says new study
I see so many contradicting studies that I'm beginning to ignore them all and use simple reason.
Animal nutritionists are acutely aware of the value of minerals and vitamins in livestock health. Soils vary from place to place thus affecting the nutrition of the feed.
A good animal scientist will take stool or blood samples to check for proper nutrition and make recommended changes. These nutritional differences vary from farm to farm. No two farms are exactly alike nutritionally.
In some regions the soils are devoid of selenium or cobalt, both essential elements for animal life. Plants can grow perfectly healthy without these elements, but the people or livestock will develope nutritional disease, such as white muscle disease.
Livestock properly supplemented will pass the missing elements to the soils and composts. This is why organic or non-organic with manuring is better than conventional NPK fertilization.
So saying there is no difference really makes me wonder as to the methodology of the above study.
