Green manure seed was planted with a plot drill seeder. Spring green manures were planted on April 14th, and summer green manures were planted on July 6th. The plots were sprinkler irrigated to aid in germination, and furrow irrigated once after they were established, but did not receive supplemental water after that.<\/p>\n<p align=\"left\">More information about green manures appropriate for Colorado is greatly needed to help local growers. We will continue to develop different green manure options, focusing on the timing of green manures to fit into intensive vegetable production cycles in Colorado.<\/p>\n<h4 align=\"center\">Spring Green Manures<\/h4>\n<ul>\n<li>\n<div align=\"left\"><em>Barley<\/em> &#8211; cool season annual cereal grain, exceptional erosion control and weed suppression in semi-arid regions<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Oats<\/em> &#8211; cool season annual cereal, suppresses weeds, prevents erosion, scavenges excess nutrients, adds biomass<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Field Peas<\/em> &#8211; summer annual and winter annual legume, can be used as a plow-down N source, weed suppressor, forage<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Fava Beans<\/em> &#8211; spring annual or winter annual legume, relatively shallow thick taproot useful for opening up heavy soils, easily incorporated into soil, we found that fava beans are slow to establish<\/div>\n<\/li>\n<\/ul>\n<table border=\"1\" width=\"561\" cellspacing=\"0\" cellpadding=\"1\">\n<tbody>\n<tr>\n<td width=\"144\"><img decoding=\"async\" class=\"alignnone lazyload\" data-src=\"https:\/\/web.archive.org\/web\/20060907122143im_\/http:\/\/www.specialtycrops.colostate.edu\/images\/rmsofp_home_pics\/green_manures\/summer_green_manure.JPG\" alt=\"Green Manures seeded with drill seeder\" width=\"144\" height=\"162\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 144px; --smush-placeholder-aspect-ratio: 144\/162;\" \/><\/td>\n<td width=\"145\"><img decoding=\"async\" class=\"alignnone lazyload\" data-src=\"https:\/\/web.archive.org\/web\/20060907122143im_\/http:\/\/www.specialtycrops.colostate.edu\/images\/rmsofp_home_pics\/green_manures\/oats_on_7.12.04.JPG\" alt=\"Oats in mid-july\" width=\"145\" height=\"162\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 145px; --smush-placeholder-aspect-ratio: 145\/162;\" \/><\/td>\n<td width=\"144\"><img decoding=\"async\" class=\"alignnone lazyload\" data-src=\"https:\/\/web.archive.org\/web\/20060907122143im_\/http:\/\/www.specialtycrops.colostate.edu\/images\/rmsofp_home_pics\/green_manures\/barley7.12.04.JPG\" alt=\"Barley in Mid-July\" width=\"144\" height=\"162\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 144px; --smush-placeholder-aspect-ratio: 144\/162;\" \/><\/td>\n<td width=\"110\"><img decoding=\"async\" class=\"alignnone lazyload\" data-src=\"https:\/\/web.archive.org\/web\/20060907122143im_\/http:\/\/www.specialtycrops.colostate.edu\/images\/rmsofp_home_pics\/green_manures\/cover_crop_peas.JPG\" alt=\"Peas in mid-july\" width=\"117\" height=\"162\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 117px; --smush-placeholder-aspect-ratio: 117\/162;\" \/><\/td>\n<\/tr>\n<tr>\n<td>\n<h5 align=\"center\">Green manures seeded with drill seeder<\/h5>\n<\/td>\n<td>\n<h5 align=\"center\">Oats in mid-July<\/h5>\n<\/td>\n<td>\n<h5 align=\"center\">Barley in mid- July<\/h5>\n<\/td>\n<td>\n<h5 align=\"center\">Peas in mid-July<\/h5>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4 align=\"center\">Summer Green Manures<\/h4>\n<ul>\n<li>\n<div align=\"left\"><em>Sorghum-Sudangrass (aka &#8211; Sudex)<\/em> &#8211; summer annual grass, great for renewing farmed out soils, weed and nematode suppressor, subsoil loosener , heavy producer of biomass<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Buckwheat<\/em> &#8211; summer or cool-season annual broadleaf grain, quick soil cover, weed suppressor, nectar for pollinators and beneficial insects, topsoil loosener, rejuvenator for low-fertility soils<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Forage Soybean<\/em> &#8211; edible summer legume and good nitrogen producer (up to 130 lbs\/acre)<\/div>\n<\/li>\n<li>\n<div align=\"left\"><em>Fava Beans<\/em> &#8211; spring annual or winter annual legume, relatively shallow thick taproot useful for opening up heavy soils, easily incorporated into soil, we found that fava beans are slow to establish<\/div>\n<\/li>\n<\/ul>\n<h4>Fall Green Manures<\/h4>\n<p align=\"left\">These were not grown at the HRC in 2004 but are commonly used in this area.
