Derived from the alfalfa plant (Medicago sativa), alfalfa meal contains many of the elements your high-value plants require for optimal growth. It is a natural source of nitrogen, potassium, phosphorus, calcium and thiamine (B1), and it is rich in amino acids.
A base nutrient is the foundation of plant nutrition. It contains the bare minimum essential elements your crops need to grow: macronutrients and micronutrients in the right amounts for both the vegetative phase and the flowering phase. Emerald Harvest offers both a 2-part base nutrient and a 3-part base nutrient.
Beneficial bacteria work in the root zone to promote plant health. Beneficial bacteria help to break down organic matter into plant-available essential elements, making the nutrients you are feeding your plants more accessible and easy to absorb.
Beneficial microbes are responsible for nutrient recycling. They decompose plant residues and other organic byproducts in the growing medium and rhizosphere, and thereby convert them into bioavailable nutrients. Consisting of beneficial bacteria and fungi, beneficial microbes can improve soil fertility and crop productivity.
Calcium is a secondary essential macroelement that helps lengthen roots and build strong plant cell walls. Symptoms of calcium deficiency are sometimes noted in plants, especially those grown in coco coir.
Carbohydrates (a.k.a. “sugars”) are an important source of fuel for hydroponic crops. Carbohydrates feed the beneficial microbes in the root zone. Some carbs are also taken up by the plant through the roots. Growers use carbohydrate supplements to give their plants more energy during budding and flowering.
Some of the microelements needed by your plants for healthy growth, such as copper and iron, cannot be easily absorbed unless they are chelated (i.e., they form a bond with a larger, organic molecule). Chelated micronutrients are often combined into complexes, so they can be absorbed and used by the plants. A chelator is the […]
Chemical symbol: Co Cobalt is a naturally occurring trace element. Considered an essential component of several enzymes and co-enzymes, it has been shown to affect growth and metabolism of plants by interacting with other elements to form complexes.
The 14 essential elements (also called essential plant nutrients) are those your plants require in order to grow. The three primary macronutrients are nitrogen, phosphorus and potassium. The three secondary macronutrients are calcium, sulfur and magnesium. The micronutrients (also called trace minerals) are boron, chlorine, manganese, iron, zinc, copper, molybdenum and nickel. Plants also require […]
All of the elements found in hemp play an important role in plant growth. The hemp seed flour used in Emerald Harvest products is derived from the seeds of Cannabis sativa itself. A complete protein, our hemp seed flour is a rich, natural source of nitrogen, amino acids, vitamins and enzymes.
Humic acids are complex organic molecules that are produced by decomposing matter. They are one of the factors that contribute to fertility in soil. Among their many chemical benefits, humics bind ions and then release them over time, which means that humic acids allow your plants to gradually uptake the nutrients they need.
Chemical symbol: Fe Iron is an essential micronutrient that helps chlorophyll form in your plants. A plant uptakes iron in its oxidized form, preferably by means of chelation. Symptoms of iron deficiency include pale, yellowing leaves and dieback.
One of the building blocks of proteins, L-form amino acids act as a chelator for nutrients, so that they can be more easily absorbed by the roots and used. L-form aminos also help your plants recover from environmental stressors, increase the chlorophyll concentration in leaves, and play a role in flowering and fruiting. Only L-form […]
The essential elements (also called essential plant nutrients) are those that your plants require in order to grow. The three primary macronutrients are nitrogen, phosphorus and potassium. The three secondary macronutrients are calcium, sulfur and magnesium. Your plants need larger amounts of these nutrients than they need of micronutrients.
Chemical symbol: Mg Magnesium is a secondary essential macronutrient, it helps your plants activate enzymes and metabolize carbohydrates. Symptoms of magnesium deficiency include older leaves suffering from chlorosis and younger leaves failing to thrive.
Chemical symbol: Mn Manganese is a micronutrient that activates enzymes in plants. It also is essential for plants during photosynthesis in order to manufacture chlorophyll. Along with iron, manganese works to create chlorophyll.
Microbial inoculants are products that introduce beneficial bacteria and/or fungi to the root zone (or rhizosphere) of your plants. They assist your plants in building up root mass, which results in greater nutrient uptake.
The essential micronutrients (also called trace minerals or trace elements) are boron, chlorine, manganese, iron, zinc, copper, molybdenum and nickel. Although required in lower quantities than primary and secondary macronutrients, they are just as essential for plant growth.
Chemical symbol: Mo Molybdenum is an essential micronutrient that helps plants utilize available nitrogen. A minimal amount of molybdenum is required in plant tissues for normal growth. Crops high in molybdenum can be toxic to ruminant animals.
Chemical symbol: N Nitrogen is one of the three primary macronutrients. In gardening, nitrogen is the element that is most often credited for strong vegetative growth. It helps plants grow vigorously and produce a heavy yield. Among other things, nitrogen is essential for the synthesis of amino acids, which are the building blocks of proteins.
A nutrient supplement is used as an add-on to a base nutrient. Nutrient supplements can boost yields, strengthen plants and correct nutritional deficiencies. They cannot be used alone to produce a healthy crop, but their addition to a base nutrient series brings many benefits to the plants.
Nutrient uptake is absorption of nutrients by the plant roots. The roots absorb water and nutrients that are either available in the growing medium or fed to crops. After absorption, nutrients are transported all the way through the plant and used for vegetative growth, flowering and metabolism.
Chemical symbol: P One of the three primary macronutrients, phosphorus is essential for healthy plant growth. It contributes to developing long roots for better access to other nutrients. Phosphorus also helps plants use energy for fruiting and flowering. Symptoms of phosphorus deficiency include slow or stunted growth and bluish leaves.
Chemical symbol: K One of the three primary macronutrients, potassium helps plants grow strong cell walls, which in turn allows them to produce heavier yields. It also aids in efficient water use. Symptoms of potassium deficiency include weak growth and limp stems.
The rhizosphere is the environment made up of the roots, the bacterial and fungal communities that live within and immediately around them as well as the growing medium immediately adjacent to the roots. It typically has a more acidic pH than the remainder of the growing medium.
Seaweed (specifically kelp varieties) is a naturally occurring, nutrient-rich algae containing amino acids. Nutrients found in this extract include potassium, calcium, magnesium and many trace elements. Powders and extracts from seaweed are often used as garden supplements to improve overall growth and plant health.
Chemical symbol: Si Silica (referred to in its elemental form as silicon) is a nonessential trace element. It helps plants create stronger plant cell structures that better support heavy fruits and flowers. It also helps your crops resist environmental stresses, pests and diseases.
Trichomes are the fine hairs or prickles on plants. On some species of plant, the trichomes gather aromatic resins, which is why trichomes are highly prized by growers and considered a key indicator of crop quality and potency.
The first major phase of your crop’s life cycle, “veging” consists of an early and a late stage. It is during the vegetative phase that the bulk of the green upper plant mass develops prior to the onset of budding and flowering.
Also called thiamine, vitamin B1 is linked to greater plant energy and root growth. It also helps to nourish beneficial microbes in the rhizosphere. Vitamin B1 has been used by horticulturists to assist in strong root initiation and development.
Chemical symbol: Zn An essential micronutrient, zinc is important to plant enzymes and crop use of proteins. Symptoms of zinc deficiency include shorter stems and reduced growth and fruiting.
