How To Use Pee In Your Garden If you can get over the ewwww factor, pee-cycling your own urine into the garden makes good sense. Fresh urine is high in nitrogen, moderate in phosphorus and low in potassium and can act as an excellent high-nitrogen liquid fertilizer or as a compost accelerator. Components of Urine The exact breakdown of urine varies depending on the diet of the pee-maker. The more protein a person consumes, the more nitrogen will be excreted into the urine. Urine also contains salt – sometimes quite a lot of it if you are hopped up on a diet of canned soup and french fries. Keep in mind that areas with a lot of rain (Seattle!) Fresh pee can have a pH anywhere from 5 to 9 depending on a person’s diet, but it tends to move toward neutral as it ages and breaks down when applied outside. Safety Issues In a healthy person, urine is sterile. If you are on medication, don’t fertilize with your pee. Grossness Issues Here’s a few other things to think about: 5 Ways To Use Pee In The Garden 1. 2. 3. 4. 5.
Principles of Terrestrial Ecosystem Ecology - Pamela A. Matson, Peter M. Vitousek, M. C. Chapin Soil and Health Library Typologie des sols On distingue généralement cinq types d'horizons : » L'horizon A est un horizon de surface, constitué surtout de matières organiques et soumis à un fort lessivage qui l'appauvrit en éléments fins et en fer. » L'horizon B est un horizon enrichi par illuvion en éléments fins et amorphes : argiles, oxydes de fer et d'aluminium, humus. Cet horizon est souvent appelé horizon structural ou horizon d'altération. Il diffère de l'horizon A par sa structure et de la roche-mère par son plus fort degré d'altération (présence de Fe2O3 libre). » L'horizon C est un horizon correspondant au matériau originel à partir duquel se forment les horizons A et B supérieurs. » L'horizon G est un horizon de couleur gris verdâtre, caractéristique des sols hydromorphes, riche en fer ferreux, avec des taches de couleur rouille (fer ferrique) se formant au contact de l'oxygène encore présent dans la zone de battance de la nappe phréatique. 1) Les sols salins. 2) Les podzols et les sols podzoliques. 4) Les sols rouges. . .
Diagnosis Of Mineral Deficiencies In Plants By Visual Symptoms - Wallace, 1943 The processes concerned in the growth of plants are the subjects of study by plant physiologists and plant biochemists. A comprehensive account of these processes is outside the scope of the present work, the special object of which is to deal with the outward and visible signs of imperfections in the plant's activities caused by faulty mineral nutrition. Nevertheless it is useful to have before us the general features of the main processes involved and to realize that the symptoms we shall be discussing later have a physiological basis, and are not direct and unchangeable signs of the specific deficiencies but result from the derangement of the complicated mechanism of the plant's vital activities. The main processes involved in plant development may be summarized as follows: Absorption: Intake of water and mineral elements by the root system. With all plants there are well defined seasonal growth cycles. Major elements: Nitrogen, phosphorus, calcium, magnesium, potassium, sulfur.
Soil Quality: Basics: Ecosystem Stability Home > Basics > Ecosystem Stability Resistance and resilience: the relationship between stability and sustainability Ecosystem stability is an important corollary of sustainability. Over time, the structure and function of a healthy ecosystem should remain relatively stable, even in the face of disturbance. Stability has two components: Resistance - the ability of the ecosystem to continue to function without change when stressed by disturbance. (Odum, 1989; Seybold et al, 1999) Factors affecting stability: Suggested practices to increase agroecosystem stability and function: Disturbance and stability An ecosystem disturbance can be natural or human induced stress. Redundancy in ecosystem structure and function often infers stability on a system. Because agroecosystems have reduced structural and functional diversity, they have less resilience than natural systems (Gleissman, 1998). Gleissman, S.R. 1997. Odum, E.P. 1989.
Online Tool For Diagnosing Tomato Problems Posted on 01 July 2008 by tomatocasual.com By Michelle Fabio A world free of tomato-growing problems would be perfect indeed, but Tomato Casual has found a fabulous online tool for when your leaves show brown spots with yellow halos or the blossom ends of your tomatoes turn black. The Tomato Problem Solver from the Aggie Horticulture team at Texas A & M can help you diagnose and treat your tomato growing difficulties. From the home page of the user-friendly Tomato Problem Solver, you can choose a general tomato disorder from the choices: Green Fruit, Ripe Fruit, Leaf, Stem, and Root. From there are you taken to a series of photos that show the most common problems tomato growers encounter. Simply choose the photo that best matches the issue you’re having, and the Tomato Problem Solver will tell you the name of the problem, its symptoms, and also how to control the damage. By the way, if you’re curious about those brown spots with yellow halos?
Suds en ligne : Les fonctions du sol La diversité des sols Les sols sont très divers, à l'échelle continentale et à l'échelle locale ; cette diversité est fonction des facteurs de formation des sols : Les sols naissent à partir des roches : les sols sont donc divers en fonction de la diversité des roches ; Les sols sont le produit de l'altération des roches par l'action de l'eau et par l'action de la vie : les sols sont donc divers en fonction des climats et en fonction des couverts végétaux ; Les sols contribuent à la formation des reliefs : les sols ne sont pas les mêmes à l'amont et à l'aval d'un versant ; Les sols évoluent au cours de leur histoire : les sols ne sont pas les mêmes selon leur âge ; Les sols sont utilisés de manières diverses par les sociétés humaines : ils ne sont pas les mêmes selon les sociétés humaines qui les utilisent et leur durée d'utilisation. Au sein d'un paysage, par exemple un bassin versant, des sols très différents peuvent être reliés entre eux de manière fonctionnelle.

Experimenting With Ollas May 28th, 2009 The area of Central Texas where I live is under severe drought restrictions. Our well draws water from an underground lake called the Edwards Aquifer which requires rain to fall in a specific recharge zone for it to refill. Because of the dry conditions over the last few years, the aquifer is drastically low. To help ensure there is enough water to go around, our water conservation district is limiting ground water users to 3,000 gallons per person each month along with other restrictions such as watering plants by hand only. Ollas (pronounced oh-yahs) are one of the oldest and most water efficient irrigation techniques available. As a small experiment, I planted two beds this spring with identical vegetables – one with ollas and a control bed without. Making Ollas Olla-making supplies: Unglazed terra cotta pot (2 per olla), tile, silicone. To seal the bottom hole, I used a peice of broken tile glued in place with silicone. Ollas vs. Olla buried in the garden.
