2016 International Permaculture Day is using this phrase: feed soil and people with pulses! What are Pulses and what do they do?!
Pulse crops Pulse: from the Latin puls meaning thick soup or potage, pulses are the edible seeds of plants in the legume family. Technically, the term “pulse” is reserved for crops harvested solely for DRY SEED.That would be DRIED peas, edible beans, lentils and chickpeas/garbanzo. Pulses are very high in protein and fibre, low in fat.
Importantly, pulses are nitrogen-fixing crops that improve the environmental sustainability of annual cropping systems. Many of you know that means they take Nitrogen from the air, ‘fix’ it in little nodules on their roots, in essence, gather their own Nitrogen, N being what plants need to live and grow. Planting these crops densely feeds your soil.
There’s more!!! Pulse Canada has gathered the data!
- Pulse crops produce a number of different compounds that feed soil microbes and benefit soil health.
- Pulse crops have a significant impact on soil biology, increasing soil microbial activity even after the pulses are harvested.
- Pulses have also been shown to exude greater amounts and different types of amino acids than non-legumes and the plant residues left after harvesting pulse crops have a different biochemical composition (e.g. Carbon/Nitrogen ratio) than other crop residues.
- The ability of pulses to feed the soil different compounds has the effect of increasing the number and diversity of soil microbes.
Definitely crops grow better in soils that are more “alive” with a diverse array of soil organisms! These organisms break down and cycle nutrients more efficiently, feeding the crops as they grow, helping crops to access nutrients.
In addition, a large, diverse population of soil organisms ‘crowds out’ disease-causing bacteria and fungi, making for healthier plants. Growing pulses breaks disease, weed and insect cycles. But of course!
Growing pulse crops in ROTATION with other crops enables the soil environment to support these large, diverse populations of soil organisms. That’s why we grow ‘green manure’ crops – bell beans (a small variety of fava), Austrian peas, vetch mixes – over winter to feed upcoming summer crops. When you remove plantings of peas or beans, cut them off at ground level rather than pull and remove those roots with the valuable nodules!
When & Where to Plant Other than for food, plant pulse soil feeding cover crops, green manure, when you want to take a break. Don’t just let your land go, give it something to do while you are away. Let it feed and restore itself! It’s so easy to do. Just wet the seed with an inoculant & fling the seed about! Keep the seedlings moist until they are up a bit, then all you have to do is water once a week or so, the plants will do the rest. If your climate is warm enough, plant one area each winter. Let it rest from other soil using crops. Plant where you will grow heavy feeders like tomatoes the following summer.
Pulses provide a number of nutritional benefits that positively impact human health! Pulse is gluten-free, can reduce “bad” cholesterol, has a low glycemic index, and virtually no fat! See more!
Pulses taste great. Rich in fiber and protein, they also have high levels of minerals such as iron, zinc, and phosphorous as well as folate and other B-vitamins. High in protein, they reduce the environmental footprint of our grocery carts. Put it all together? Healthy people and a healthy planet.
Pulses come in a variety of shapes, sizes and colours and can be consumed in many forms including whole or split, ground into flours or separated into fractions such as protein, fibre and starch. That could be delicious red bean salsa, chiles, split pea soup, plain or spiced hummus, falafel balls! Dairy free pulse cakes and cheesecakes, ice cream!
Pulses do not include fresh beans or peas. Although they are related to pulses because they are also edible seeds of podded plants, soybeans and peanuts differ because they have a much higher fat content, whereas pulses contain virtually no fat.
There are delish recipes online, and Pulse recipe books – main dishes, desserts and baked goods! Put more of these good foods in your life! Check out http://www.cookingwithpulses.com/ !
The Green Bean Connection started as correspondence for the Santa Barbara CA USA Pilgrim Terrace Community Garden. We are very coastal, during late spring/summer in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is. Bless you for being such a wonderful Earth Steward!
