{"product_id":"2940151322737","title":"Agriculture in Transition","description":"Ideas such as \"crop and soil weatherproofing,\" the \"row support system,\" and the \"tillage commandments,\" exemplify the practicality of the soil\/root maintenance program that serves as the foundation for Schriefer’s highly-successful \"systems approach\" farming. Schriefer was a pioneer in developing an awareness of the relation of tillage to soil fertility, focusing on three major soil basics — soil aeration, soil water, and soil decay. This book covers such topics as soil chemistry, plant and soil dynamics, above- and below-ground plant management, row support fertilization, zone-tillage, disc-chiseling, and more. He focuses on reducing \"yield-limiting factors\" such as seed selection, excessive tillage and a dependence on technology.","brand":"Acres U.S.A.","offers":[{"title":"Default Title","offer_id":47160813682928,"sku":"2940151322737","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940151322737_p0.jpg?v=1764009942","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940151322737","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
