Bunker silos offer many advantages over tower silos for the storage of haylage and corn silage, but require careful management to minimize fermentation and spoilage losses. Along with proper harvest moisture, length-of-cut and the use of a research proven silage inoculant, additional attention must be applied to proper site selection, sizing, filling, packing, covering, rodent […]
Red clover haylage can sometimes be a good alternative to alfalfa. Under ideal conditions alfalfa will usually outyield red clover. However, in areas where alfalfa winterkill is a problem, red clover better tolerates imperfect drainage and lower pH levels, and can be grown in fields that are too wet or low pH for alfalfa. Red clover feed […]
Reseeding alfalfa following alfalfa is not a recommended practice due to the effects of autotoxicity, and plant diseases that can build up in the old stand. Alfalfa autotoxicity occurs when established alfalfa plants produce toxins which reduce both the germination (establishment) and the growth (yield) of new alfalfa plants. Autotoxicity can occur when alfalfa is reseeded into an […]
Winterkill of forage stands is significant in many parts of eastern Ontario this spring. Both new forage seedings and older stands areeffected. A decision must be made to either keep and manage a reduced stand, or replace the stand with another crop. The first thing that forage growers need to do is to walk their […]
Frost heaving can significantly damage alfalfa plants, leaving stands with much less or even zero yield potential. Plants may initially appear undamaged, but taproots are typically broken and unable to pick up enough nutrients or moisture, and stands eventually die. Frost heaving of alfalfa happens when repeated freezing and thawing pushes the tap root and crown out of the soil. […]
Low forage inventories, high land costs, and sometimes increasing risks for alfalfa winterkill make assessing spring alfalfa health essential. Walking fields in early spring to determine if the alfalfa stand has thinned, and assessing if plants are dead or unhealthy is a proactive strategy to determine management options. Making the decision whether to manage an existing reduced stand or replace it […]
Orchardgrass can be very productive, particularly in pastures and hay fields with aggressive cutting schedules. It is a very fast growing, perennial, cool-season grass. However, because it heads so very early in the spring and then declines quickly in digestible energy and protein, it has not been as widely used for stored forage in […]
Frost seeding or the broadcasting of forage seed on frozen ground in late-winter or early-spring can be an effective way of improving the forage quality and yield of thinning pastures. It allows for the establishment of forages at reduced cost in an undisturbed sod and also shortens the non-grazing period in the spring. For frost […]
Many horse owners are finding it increasingly challenging to find and purchase suitable hay at a price they can afford. Low hay yields due to dry weather in 2012 were followed by poorer quality as a result of rainy haying weather in 2013. However, there are also long term economic factors in play that […]
Record acreages of emergency annual forages were seeded this summer after wheat and spring cereals were harvested. Low yields of first- and second-cut hay left many farmers with very low forage inventories. Emergency forages used included cool-season cereals (oats, barley, triticale) and cereal pea mixtures, as well as some warm-season sorghums, sorghum-sudans and millets […]
When we make corn silage and haylage, we are using our skills as microbiologists, just like winemakers, brewers and composters. As a biological system, silage making doesn’t always work perfectly. During an anaerobic silage fermentation, microorganisms feed on sugars and other soluble carbohydrates in the forage material and produce organic acids, such as lactate and […]
Compiled by Chris Brown, edited by Horst Bohner 2012 Soybeans were originally introduced to Ontario as a forage crop for cattle. Today, the vast majority go for crush and the IP market. Letting the crop mature and harvesting the seed is far more profitable than using it as a forage crop but in some cases […]
Farmers exposed to silo gas (nitrogen dioxide, NO2) are at risk of severe respiratory distress, permanent damage to lungs, and even sudden death. It is difficult to predict when silo gas will be produced, so always take precautions following harvest. Weather conditions and agronomic practices affect the amount of nitrates in plant material, which set the stage for […]
It can be very tempting to cut some alfalfa for haylage or baleage in the fall, particularly when supplies are tight or there is a lot of growth. The decision to cut or not needs to weigh the immediate need for forage against the increased risk of alfalfa winterkill and reduced yields next spring. How do […]
Extended periods of dry weather without rain can severely stress corn plants. When this occurs during tasselling and pollination, cob formation and grain yield can be significantly reduced. As the situation worsens, leaves turn brown and the plants can appear dry and “dead”. Some farmers attempt to salvage this corn by using it as forage […]
