Experts: Pasturing Is Agronomic Art (Continued from Page AM) grow soybeans, cam, alfalfa, but have forgotten how to grow grass,” he said. ’Timing is key. It’s (a matter of knowing) why it happens and when it happens,” Craig said. According to Craig, key. to understanding the potential of pas turing, is to understand die plants themselves what time of year and how often they can be grazed. It is also key that a farmer con sidering increasing the use of pas tureland must be realistic. Craig said. “Instead of trying to make things grow where they’re not sup posed to grow,” Craig said, pro ducers should concentrate on areas where forage production is possible. In his preview. Craig said that three things have to come together in order for pasturing to work the needs of the plant being for aged, the needs of the animal, and the abilities of the producer. “By understanding the basics, you get an understanding of every thing else,” he said. Pysher, in trying to make a point' that pastures need to be cultivated in order for them to provide the types of returns and dependability that is needed to support livestock production, joked that he was sure that pastureland was sacreo ground it had to be, he said, ”... because the lime and fertilizer buck are never allowed anywhere near it” The major goal of prescribed pasturing is to provide quality for age for grazing animals throughout the growing season. Also, he reiterated what Craig said about effective pasturing being a combi nation of meeting the needs of the animal with the needs of the plant The key, according to all speak ers, was the farmer himself the farmer’s ability to keep records, his efforts to leam about the plants that may work into a program on ROOTWORMS BEWARE.

I his specific Cum, and hit ability to realistically analyze his land’s potential. The end result is not an isolated practice, but an integral practice, if pasturing is to be done correctly. The end result is a grazing system. Pysher reviewed the basics of plant growth, but emphasized the difference between managing plant growth feu condnous grazing stand production, and managing plant growth for fall harvest The difference is in understand ing how plants operate. Of the sunlight, water and car bon that plants combine into growth, a certain portion of the carbohydrates manufactured dur ing pbolosynthisis is stored in the root system as reserves. It is these reserves that an estab lished plant uses to generate new growth, once the stems and leaves have been lost, either through season-end die-back, or through removal by grazing or cutting. If the plant is grazed too often, the root reserves are drained, resulting in plant death or poor per formance. If the plant is grazed too far down to the ground, the growth zone is removed and further growth must come from the base of the plant, or the root, which requires more energy by the plant If the plant is not grazed soon enough, it will go into its reproduc tive stage and lose its feed qualities. Balancing the management of the animals, with the management of the forage plants is the role of the producer. Pysher talked briefly about a couple of different types of forage plants most commonly in use, such as Kentucky Bluegrass, and he described its reserve energy stor age in shallow roots called rhizomes. He compared that with Orchard Grass, which typically stores its regrowth energy above the soil COUNTER* 20CR* systemic insecticide-nematicide gives com growers all the most desirable insecticide features in one outstanding product.

If a producer allows an animal to graze the plant below that point, there is no reserve for regrowth. “You have to understand the morphological differences,” he also said, between a plant in its vegetative stage and its reproduc tive stage. Although, none of the experts used the analogy, anyone who has raised and harvest aspargus, knows that the edible part is the shoot, and a single plant can send up a number of shoots during a sea', son„ allowing for a relatively long harvest period. If the asparagus plant's shoots aren’t cut off, and die shoot is allow to grow, the plant goes into its reproductive stage, which resemebles a green leafy bush, and eventually goes into seed production. Similarly, the grasses, legumes, brassicas, and other plants which can be used to establish a produc tive pasture are used to forage while in the vegetative stage, when moisture, energy, palatibility, and digestabUity are high in quality, and yield is still good. There is more yield in allowing a plant to go into the reproductive stage, but the quality for forage is low, and the plant isn’t as likely to respond well. The balancing act comes at try ing to graze a particular plant after it has reached a height that is pro tective of its regenerative abilities near the soil, but not yet mature enough to begin developing tough structural matter. Dr. Hall, who has published much of the findings of Dr. Jung’s 35 years of work with pasture research for Extension use, dis cussed improving pasture produc tivity, specifically as to the funda mentals of cool season forage crops. According to Hall, generally through a season, there are two Uncwiar Farmktg, Saturday, March % IN4-A3 periods of growth in the spring into early summer, and again from the fall into early winter. The sum mer slump, when there is no growth, .is something producers have to learn to live with. While Hall doesn’t necessarily recommend that beginning pastur ets concern themselves with some of the plants which can be also raised in a pasture to provide sum mer forage, he said there is poten tial using warm season grasses and brassicas to attend pasture use lon ger into summer and fall. Hall outlined the fundementals of timing with grazing, talking about the quick rcgrowth of spring and the shorter intervals of rest required for a pasture between grazings during that time. He said that cool season peren nials are the backbone of pasturing in Pennsylvania, and they need to be nurtured just as well. He suggested taking soil tests, sampling no deeper than three inches. He also talked about identifying existing plants, and techniques for creating an established pasture. Fertilization, grazing and haying, and weed control arc issues to be concerned with, he said. Poor fertilization results in weeds outcompeting desired plants. The timing of grazing arid haying is as critical as though alfal fa was being harvested for maxi mum protein and energy. He gave a number of specific tips on management, all of which are available through Extension services. He warned against puting manure on young legumes, which actually helps the grasses and weeds to growth, not the legumes; applying fertilyzer after first graz ing. or an August grazing; and redefining the term, “weed.” For example, a variety of chick ory, commonly considered a weed, and which previously required a permit to raise, can now be grown because of its nutritional value as livestock feed. Hall calls diem forage weeds. “Generally, weeds do not influ ' ences a pasture persistence, once the pasture is established,” he said, adding that, like other established stands of plants, eventually pests, poor soil fertility, or poor grazing management can destroy the stand and allow an opportunity for weeds to become established. In his talk. Jung discussed the, variety of plants which can and perhaps should be found in a pas ture, because of the animal bene fits. He said there are a number of different plants which can provide minerals in good quantities, in addition to plants which provide energy and protein. He also talked about some var ieties of plants, such as the brass!- cas, which can be used for late fall grazing, and switch grass, a native grass, which has demonstrated some remarkable abilities to pro vide forage. In fact, he said that in Switzer land, producers were trying to imi tate American dairy production and reduced the number of verities of plants in pasture to one or two. They experienced a number of ani mal health and nutrition problems, he said. USDA Seeks Comment WASHINGTON, D.C. The U.S. Department of Agriculture is inviting dairy farmers, milk cooperative associations, milk handlers (shippers) and consum ers to testify at a hearing on prop osals to amend the Middle Atlan tic federal milk marketing order. The hearing will begin on May 2 at 9 a.m., at the Holiday Inn- Independence Mall, 400 Arch Street, Philadelphia, Pa. Lon Hatamiya, administrator of USDA’s Agricultural Marketing Service, said a federation of dairy ■producer cooperatives, which requested the hearing, proposes to amend the order’s “pooling” pro visions. At issue are the rules for amounts of milk its members must deliver or distribute under the order to be eligible to receive the order’s benefits, he said. The Middle Atlantic milk mark eting order affects northern Virgi nia, eastern Maryland, southeast ern Pennsylvania, Delaware, southern New Jersey, and the Dis trict of Columbia. Details of the hearing were pub lished as a notice in the March 4 Federal Register. Copies of the notice are available from Rex F. Lothrop, Market Administrator, Suite 200 Essex Building, 333 N.
