Winter Pea Inoculation: Austrian Peas' Need For Nutrients

Austrian winter peas are a cool-season annual legume that can be planted as a cover crop or by home gardeners. They are easy to grow and quick to germinate, and they have the same nitrogen-fixing abilities as garden peas, which can help reduce fertiliser use. However, there is some debate among farmers and gardeners about whether Austrian winter peas need an inoculant. Some sources suggest that inoculants are necessary for the peas to fix nitrogen effectively, while others claim that the peas will grow without it, depending on the quality of the soil. Ultimately, the decision to use an inoculant may depend on individual preferences, soil conditions, and the desired outcomes for the crop.

Inoculating Austrian winter peas can save money on fertiliser

Austrian winter peas are a cool-season annual legume that can be planted as a food plot or cover crop. They are easy to grow, quick to germinate, and highly attractive to deer and other wildlife. When planted as a stand-alone crop, Austrian winter peas do not require much nitrogen fertiliser because, as legumes, they are able to fix their own nitrogen from the soil.

Inoculating Austrian winter peas with the correct strain of rhizobium bacteria can aid in nitrogen fixation. The inoculant is a species-specific bacteria that allows the plant to fix nitrogen. If there are not enough bacteria, there is limited nitrogen production from the legume plants. A healthy Austrian winter pea cover crop can produce nearly 200 units of nitrogen.

Inoculants convert nitrogen in the atmosphere into a usable form for the plant, a process known as "fixing" nitrogen, and will also promote vigorous, healthy growth. When purchasing Austrian winter pea seeds, it is best to look for inoculated seeds. Alternatively, you can purchase an inoculant and inoculate your own seeds.

Inoculants are specific bacteria that allow plants to fix nitrogen

However, legumes cannot perform biological nitrogen fixation alone. This is where inoculants come in. Inoculants are soil bacteria, specifically rhizobia, that form a symbiotic relationship with legumes. In this mutualistic relationship, the rhizobia create specialised organs called nodules on the legume's roots. These nodules provide an ideal environment for converting atmospheric nitrogen into a form that the plant can use.

The effectiveness of nitrogen fixation can be assessed by examining the nodules on the plant's roots. Actively fixing nodules will be pink due to the presence of leghemoglobin, which maintains a low-oxygen environment. On the other hand, inactive or ineffective nodules will be white, indicating insufficient nitrogen availability for the plant's growth.

The specific type of inoculant required depends on the legume species being planted. For example, soybeans are associated with the rhizobium species Bradyrhizobium japonicum, while field peas form associations with Rhizobium leguminosarum. It is essential to select the appropriate inoculant to ensure the formation of nodules.

In addition to legumes, inoculants can also benefit non-leguminous crops and cereal crops. For example, Azospirillum has been shown to be beneficial for nitrogen fixation and plant nutrition in non-legume plants. In cereal crops, diazotrophic rhizobacteria have increased plant growth, grain yield, and nutrient uptake.

By applying inoculants, farmers can improve crop health, increase nutrient availability, and reduce the need for synthetic nitrogen fertilisers. This not only improves agricultural productivity but also contributes to sustainable practices by reducing the environmental impact associated with fertiliser use.

Austrian winter peas are a cool-season annual legume

Austrian winter peas perform well in nearly any type of well-drained soil, but they need consistent moisture and don't do well in arid climates with less than 20 inches of rainfall per year. They are winter hardy in USDA zones 6 and above, and seeds are typically planted in autumn, after the hottest days of summer have passed. In colder climates, the vines may need protection from a good snow cover, or they are likely to freeze. Alternatively, they can be planted as an annual in early spring.

When used as a cover crop, Austrian winter peas are often planted with a mixture of seeds such as oilseed radishes or various types of clover. They are easy to grow and quick to germinate, forming vine-like growths that can reach lengths of 3 to 5 feet when planted in fertile soil. They are highly nutritious and extremely digestible to deer, with a protein level between 20 and 30 percent.

To establish a food plot of Austrian winter peas, they can be broadcast at a rate of 50 to 75 lbs per acre in September through October, or drilled at a rate of 30 to 50 lbs per acre. In northern climates, they can be planted as early as late August, or in spring as a summer annual. After planting, the seeds should be dragged in, lightly disked, or cultipacked to a depth of no more than 1 inch.

Austrian winter peas do best on loam or clay loam soils that are well-drained, with a pH range of 6.0 to 7.0. When planted as a stand-alone crop, they don't require much nitrogen because they are able to fix their own nitrogen from the soil. This can result in a lower fertilizer bill. However, it is important to inoculate the seeds with the proper strain of rhizobium bacteria to aid in nitrogen fixation.

Peas need well-drained soil and consistent moisture

Peas are a traditional home garden crop grown all over the world. They are relatively easy to grow and do not require as much attention as other vegetables. However, they do need well-drained soil and consistent moisture to thrive.

Peas will grow in all soil types as long as they are rich in organic matter, well-drained, and fertile. The ideal soil type for peas is loamy and well-drained, with a pH level between 6.0 and 7.5. Peas are tolerant of most soil conditions but grow best in sandy to heavy clay soils.

To ensure your peas have well-drained soil, you can plant them in raised beds or containers. If you are planting in your traditional backyard garden, make sure to amend any heavy clay-like soil with organic material to improve its quality.

Peas require regular watering, especially during flowering, to maintain soil moisture. They tend to have a shallow root system, so they need a consistent supply of moisture to keep them thriving. During dry springs, you may need to water them more often. Sandy soils may also need more frequent watering.

To help maintain soil moisture and prevent weeds, you can mulch your pea plants with 3 to 4 inches of grass clippings, weed-free straw, or other organic material. Organic mulches also help conserve water, supply extra nutrients, and make it easier to control weeds.

Peas are a good source of nutrition for humans and livestock

Austrian winter peas may need an inoculant, depending on the bacteria present in the soil. Inoculants are important because they allow the plant to fix nitrogen.

Peas are indeed a good source of nutrition for both humans and livestock. They are part of the legume family, which also includes lentils, soybeans, chickpeas, and beans. Peas are a good source of plant protein and are rich in vitamins, minerals, antioxidants, and phytonutrients.

Nutrition for Humans

Peas have high concentrations of vitamins, minerals, antioxidants, and phytonutrients, which provide a range of health benefits. For example, peas can help keep your eyes healthy and protect against certain types of cancer. The carotenoids lutein and zeaxanthin in peas help protect your eyes from chronic diseases such as cataracts and age-related macular degeneration. Additionally, peas are rich in coumestrol, which plays a role in protecting against stomach cancer. A 2009 study showed that daily intake of peas and other legumes lowered the risk of stomach cancer by 50%.

Peas are also a good source of fiber, which aids in digestion and helps control blood sugar levels. The fiber in peas can improve gut health and make stools softer and easier to pass. Additionally, peas are high in non-heme iron, which helps the body produce red blood cells that carry oxygen around the body.

Peas also have anti-inflammatory properties and can help reduce the risk of inflammatory conditions such as diabetes, heart disease, and arthritis. The omega-3 and omega-6 fatty acids in peas help reduce oxidation and inflammation and prevent plaque formation along blood vessel walls.

Nutrition for Livestock

Field peas, which are technically beans, are commonly used as livestock food, particularly for dairy cows. They are a good source of protein for cows and can be used as a partial substitute for soybean meal and corn grain in their diets. However, it is recommended to add extra amino acids when using field peas as a replacement.
