SQL08 – Intercropping to Improve Soil Quality and Increase Biodiversity
United States Department of Agriculture Natural Resources Conservation Service 2012 Ranking Period 1 Soil Quality Enhancement Activity – SQL08 – Intercropping to improve soil quality and increase biodiversity Enhancement Description This enhancement involves the use of intercropping principles, growing two or more crops in close proximity to each other, to promote interaction resulting in improved soil and water quality while increasing biodiversity. Land Use Applicability Cropland Benefits Incorporating intercropping principles into an agricultural operation increases diversity and interaction between plants, arthropods, mammals, birds and microorganisms resulting in a more stable crop-ecosystem. This collaboration that mimics nature is subject to fewer pest outbreaks; improved nutrient cycling and crop uptake; and increased water infiltration and moisture retention. Soil quality, water quality and wildlife habitat all benefit. Conditions Where Enhancement Applies This enhancement applies to all crop land use acres. Criteria One or more of the following intercropping systems will be used; systems can be mixed during the contract period allowing for a different system to be used each year on the same field. 1. Relay inter-cropping – the growing of two or more crops on the same field with the planting of the second crop after the first one, e.g. over seeding of a clover cover crop into cotton during defoliation, or planting of clover at lay by time of corn. 2. Row inter-cropping – the growing of two or more crops simultaneously on the same field with at least one crop planted in rows, e.g. planting corn in the rows and inter-seeding sorghum between the rows, harvesting all as silage or planting clover in between orchard tree rows. -

What Was the Effect of New Crops in the Agricultural Revolution? Evidence from an Arbitrage Model of Crop Rotation
What was the Effect of New Crops in the Agricultural Revolution? Evidence from an Arbitrage Model of Crop Rotation Liam Brunt1 Abstract In this paper we develop an arbitrage model of crop rotation that enables us to estimate the impact of crop rotation on wheat yields, using only the yields and prices of each crop employed in the rotation. We apply this technique to eighteenth century England to assess the importance of two new crops – turnips and clover – in raising wheat yields. Contrary to the received wisdom, we show that turnips substantially pushed up wheat yields but clover pushed down wheat yields. We confirm this result by comparing our estimates to both experimental data and production function estimates. Further detailed analysis facilitated by the new model enables us to explain this surprising result in terms of the management practices pursued by farmers. Keywords: agriculture, crop rotation, technological change. JEL Classification: N01, N53, O13, Q12. 1 I would like to thank James Foreman-Peck and Lucy White for helpful comments. Any remaining errors are my own responsibility. An arbitrage model of crop rotation 2 I. Introduction. The defining feature of the Industrial Revolution in England was the transfer of labour resources from agriculture to industry, which occurred exceptionally early by international standards.2 But England had to remain virtually self-sufficient in food production during the eighteenth century because very few exportable surpluses were being generated by other European countries.3 The adoption of new technology was a crucial factor that permitted England to attain a high level of agricultural labour productivity – which in turn facilitated labour release.4 The number and range of innovations coming into general use in the eighteenth century has prompted commentators to dub it the period of the ‘Agricultural Revolution’.5 There were new animal breeds (the Shire horse and the dairy short horn cow); new crops (turnips and clover); new machines (seed drills and threshers); and new hand tools (the cradle scythe). -

Classification of Botany and Use of Plants
SECTION 1: CLASSIFICATION OF BOTANY AND USE OF PLANTS 1. Introduction Botany refers to the scientific study of the plant kingdom. As a branch of biology, it mainly accounts for the science of plants or ‘phytobiology’. The main objective of the this section is for participants, having completed their training, to be able to: 1. Identify and classify various types of herbs 2. Choose the appropriate categories and types of herbs for breeding and planting 1 2. Botany 2.1 Branches – Objectives – Usability Botany covers a wide range of scientific sub-disciplines that study the growth, reproduction, metabolism, morphogenesis, diseases, and evolution of plants. Subsequently, many subordinate fields are to appear, such as: Systematic Botany: its main purpose the classification of plants Plant morphology or phytomorphology, which can be further divided into the distinctive branches of Plant cytology, Plant histology, and Plant and Crop organography Botanical physiology, which examines the functions of the various organs of plants A more modern but equally significant field is Phytogeography, which associates with many complex objects of research and study. Similarly, other branches of applied botany have made their appearance, some of which are Phytopathology, Phytopharmacognosy, Forest Botany, and Agronomy Botany, among others. 2 Like all other life forms in biology, plant life can be studied at different levels, from the molecular, to the genetic and biochemical, through to the study of cellular organelles, cells, tissues, organs, individual plants, populations and communities of plants. At each of these levels a botanist can deal with the classification (taxonomy), structure (anatomy), or function (physiology) of plant life. -

Guidance for Designing a Compliant Crop Rotation
Guidance for Designing a Compliant Crop Rotation Crop rotation is an important cultural method for managing nutrients, combating pests, and protecting vital natural resources. Rotations designed using knowledge of plant biology, weed cycles, and nutrient cycling can boost yields and provide investments in soil fertility. It is important to consider, however, that while crop rotation has formal and informal meanings, NOP defines crop rotation as “the practice of certified organic operators are required to alternating the annual crops grown on a specific field in a planned pattern or sequence in create a crop rotation as defined through the successive crop years so that crops of the same National Organic Program (NOP). Certifiers, species or family are not grown repeatedly such as PCO, evaluate whether a crop rotation without interruption on the same field. Perennial is compliant with organic regulations based on cropping systems employ means such as alley the regulatory definition and several standards cropping, intercropping, and hedgerows to that refer to crop rotation (7 CFR 205.203, introduce biological diversity in lieu of crop 205.205 and 205.206). rotation.” (7 CFR 205.2) Crop rotation: a functional standard Crop rotation is a required practice in the NOP organic regulations. Generally, crop rotations are planned to take advantage of inherent crop characteristics that will benefit the land, the farmer, and subsequent crops. While there are multiple strategies and possibilities for rotating crops in a given field over time, there are specific functions that must be considered during its design and implementation. PCO will look at your rotation to determine whether it fulfills the following criteria: (1) Maintains or improves soil organic matter; (2) Assists with the management of pests in annual and perennial crops; (3) Manages deficient or excess plant nutrients; and (4) Provides erosion control. -
