No full textLes données résultent de l’évaluation expérimentale de 4 systèmes de culture.
Les objectifs du Système Productif à Hautes Performances Environnementales (PHPE) sont de satisfaire un ensemble de critères environnementaux (réduction de la pollution par les pesticides et nitrate ; augmentation de la biodiversité implantée) quantifiés et d’atteindre, dans ce cadre, une production élevée. Pour les trois autres systèmes, au respect des objectifs environnementaux du système PHPE s’ajoute une contrainte environnementale forte supplémentaire. Dans le Système Sans pesticide (SsPest), il est interdit d’utiliser tout traitement phytosanitaire (produits chimiques de synthèse et produits autorisés en agriculture biologique). Dans le Système Energie moins (ENm), la consommation d’énergie fossile doit être réduite de moitié à l’échelle du système par rapport au système PHPE. Dans le Système Gaz à Effet de Serre moins (GESm), les émissions de gaz à effet de serre doivent être réduites de moitié par rapport au système PHPE. Pour ces trois derniers systèmes, les niveaux de production seront aussi élevés que possible compte tenu des contraintes et objectifs environnementaux assignés.
Cette évaluation sur le long terme (12 ans : 2009-2020), initiée en 2008, se déroule sur une parcelle de plus de six hectares, sur des sols limoneux, très homogènes et profonds (profondeur supérieure à 1,80m) de la ferme d’AgroParisTech à Grignon (78, France : N 48.84°, E 1.95°).
Le dispositif comporte trois répétitions pour chacun des quatre systèmes, et la surface élémentaire des parcelles est de 4100m². Compte tenu de la forte homogénéité du sol, la variabilité interannuelle du climat a été privilégiée. Chaque année, chaque système de culture est représenté par une culture différente de la succession dans chacun des blocs.
Dans ce dispositif, des mesures nombreuses visent en premier lieu à évaluer la capacité des systèmes de culture à satisfaire les contraintes, les objectifs environnementaux et les niveaux de production assignés. Des diagnostics agronomiques appropriés permettent également de comprendre les raisons de ces performances. Les évolutions à moyen/long terme des caractéristiques physiques (état structural des sols,…), chimiques (teneurs en éléments minéraux, en pesticides et en matières organiques des sols) et biologiques (communautés de vers de terre et d’arthropodes, microflore des sols, peuplement d’adventices,…) du champ cultivé sont caractérisées et analysées pour évaluer les conséquences des systèmes expérimentés sur l’évolution des milieux.
Les données disponibles sont complémentaires à celles publiées dans divers data papers et disponibles dans data.gouv.
Ici sont aussi retranscrits les règles de décision définies en début de période expérimentales pour conduire de façon technique les différents systèmes de culture

BIOGRAPHICAL / Historical Note: Twentieth-century novelist Caroline Gordon was born into the Kentucky line of the extensive Meriwether family in 1895. Exploration of the family's past and its evolution is a major theme of her fiction. She grew up at Merry Mont in Todd County, near Clarksville where she received her early education. She earned a Bachelor of Arts degree from Bethany College in 1916. Her father is the idealized subject of Gordon's second novel, Alec Maury, Sportsman (1934), and the central character in her much-anthologized story, "Old Red." Gordon taught briefly; then, as a journalist, she became one of the first reviewers to comment favorably on a new Nashville-based magazine of poetry, The Fugitive. During the summer of 1924, Robert Penn Warren, a Todd County neighbor, introduced her to Allen Tate. Within a year they were married and living in New York City, where their daughter, Nancy Meriwether was born. With Tate, she began a period of life abroad, devoted to writing and sustained by various fellowships granted to one or the other. In London, Gordon was secretary to the influential British writer Ford Madox. In 1930 the Tates returned to the United States and settled in Clarksville in a house provided by Tate's brother Ben and called "Benfolly." Both Tates were exceptionally hospitable to friends and encouraging to younger writers. Both were prolific correspondents, generous with constructive criticism. (Gordon eventually became mentor to several writers, most notably Flannery O'Connor). Although she had to wrest time for her writing from domestic and social obligations, the eight Benfolly years were especially productive for Gordon, who published four novels and several stories before 1937. The first novel was Penhally (1931), followed by Alec Maury, Sportsman (1934), None Shall Look Back (1937), and The Garden of Adonis (1937), studies of the southern family during the Civil War and Great Depression. Academic appointments of the 1940s took the Tates throughout the Southeast and to Princeton, where they established a home near their daughter, who married psychiatrist Percy Wood in 1944. During this time Gordon published her fifth novel, Green Centuries (1941). Her second related group of novels, The Woman on the Porch (1944), which deals with a troubled marriage, The Strange Children (1951), based on life at Benfolly, and The Malefactors (1956), is informed by her conversion to Roman Catholicism. She and her husband wrote The House of Fiction (1950), which was followed by Gordon's How to Read a Novel in 1957. Gordon lived in Princeton until 1973, teaching, and writing: The Glory of Hera (1972). An appointment in the creative writing program drew her to the University of Dallas (Gordon was 77 years old when she proposed the new creative writing program at UD). When her health began to fail in 1978, she moved to San Cristobal de las Casas in Chapas, Mexico, with her daughter and family. She died there on April 11, 1981.
