Stabilizessoil surface, reduces soil compactionTillage of alternate rows, of vineyard and orchards, thereby reducingpasses across field.Bed-row size or spacingIncrease or decrease the size ofthe planting area bed (can bedone for field and permanentcrops)Reduces the number of passes and soil disturbance byincreasing plant density/canopy thru reduction of rowwidth, overhead vineyard production systems,containment of PM within canopyPlanting multi- rows on a wide bed, e.g. tomatoes or melons 2- rows on60", Narrow row planting of cotton can reduce two to three cultivationpasses; overhead vineyard system of vineyards can reduce cultivationand pesticides by shading unwanted vegetation that reduces the need forcultivation and pesticides, other planting systems may have similarbenefits, including but not limited to using 80" wide-bed system as wellas a 60"system for either cotton or vegetable planting.Chemigation/FertigationApplication of chemicals thru anirrigation systemEach application reduces the need to travel in-field forapplication purposes. Reduces the number of passes andsoil disturbance, increases efficiency for applicationDuring irrigation, add herbicide or fertilizer through water application;also includes aerial applicationCombined operationsTo combine equipment, toperform several operations duringone passReduction in the number of passes necessary to cultivatethe land will result in fewer disturbances to the soil. Otherbenefits are reduction of soil compaction and time toprepare fields, both of which can be precursors toadditional tillage requirementsCombining cane cutting, discing and flat- furrowing in a single pass forvineyards, use of one- pass till equipment in ground preparation or croptillage, cultivation and fertilization of field crop in a single passConservation irrigationTo conserve the quantity of wateruse, e.g.: drip, sprinkler,buried/underground lineConserves water, reduces weed population, which in turnreduces the need for tillage and reduces soil compaction.Use drip, or buried line (including permanent or semi-permanent line) incrop production, use of pressure bombs, water flow meters or soilmonitoring devices to avoid over-irrigation, using irrigation managementconsultants, adopting the use of Evapo-transpiration factorsCROPLAND -LAND PREPARATION / CULTIVATION2 List of Conservation Management PracticesPRELIMINARYCMPsDESCRIPTIONBENEFITSEXAMPLESConservation tillage (e.g.:no tillage, minimum tillage)Types of tillage that reduce lossof soil and water in comparison toconventional tillageReduces the number of passes, soil disturbance.

The lessdisturbance and handling of the litter/manure, the lessemissions. Any time poultry bedding material is moved,some of the bulk material may become airborne. Thebedding may be used for several grow out cycles beforeit becomes so laden with waste that it is unsuitable forcontinued use. Optimizing the reuse of the beddingmaterial can reduce the number of material transfers,thus the opportunity for some of the material to becomeairborne. Implementation of this CMP implies that thegeneration of dust will become a factor in thedetermination to perform a house clean-out, and morereuse of bedding is anticipated.To allow bedding materials and manure to remain in the house formultiple flocks or grow out cycles, or to decrease the frequence of housecleanouts to minimize dust emissions.Outdoor StorageTo use of a structure design tostore the bulk materials (e.g.:used poultry litter/manure) or tosecurely cover the bulk materialsif it must be stored outdoors notwithin any enclosurePrevents contact with precipitation and preventswindblown dispersion. Poultry litter consists mainly oflight organic materials such as rice hulls or woodshavings. During a poultry house cleanout the used litteris scrapped out of the house and left in piles outdoors. Ifleft in these outdoor piles for extended periods, winds cancause material to become airborne. Any technique thatwill shield the litter from wind will prevent or reduce theamount of material becoming airborne. Securely tarpingthe piles will protect the used litter from precipitation andwindblown dispersal until the liter can be removed fromthe ranch. A partially enclosed structure, with wallssituated in the prevailing wind direction, may be used toprotect used litter stored onsite from precipitation andwindblown dispersal.To employ a structure design to store used poultry litter (manure andbedding material) onsite or to cover the bulk materials with tarps, plasticsor suitable materials.POULTRY OPERATIONS - MANURE HANDLING & STORAGE13 List of Conservation Management PracticesPRELIMINARYCMPsDESCRIPTIONBENEFITSEXAMPLESBoot or sockFeed is loaded into the feedstorage bins by employing a sockor boot on the feed delivery truckaugerTo reduce the release of particulatesUse of a sock or boot on the delivery truck augerVegetationMaintaining some vegetation,such as native grasses, on vacantlandReduces windblown dust.Allowing vegetative material to grow on vacant sections of the operationReduced tillageTo reduce the number of tillingsReducing soil disturbance by stabilizing soil surfaceLeaving residue on surface after mowing, using pre-emergent or contactherbicides, scorching of weeds instead of tilling, mulch to smother weedcompetitionWindblocksTo establish a perimeter physicalbarrier to reduce windblown dust.Disrupts the erosive flow of wind over unprotected areasthus helping to reduce fugitive dustUse of perimeter physical barriers or vegetation barriers to disrupt windflowDust suppressantsApplication of any non-toxicchemical or organic dustsuppressant which meets anyspecification required by anyfederal, state, or local wateragency and is not prohibited foruse by any applicable regulations.See Regulation VII for additionalrequirementsReduces entrainment of fugitive dustTo use a variety of products: water application, hygroscopicsuppressants (road salts), petroleum emulsions, adhesives, polymersemulsions, and bituminous materials (road oil).
