all you need to know about growing hops and plants enjoy
if ya need any help pm me and ill try and help you
Macronutrients
Nitrogen (N)
Nitrogen is a part of all living cells and is a necessary part of all proteins, enzymes and metabolic processes involved in the synthesis and transfer of energy.
Nitrogen is a part of chlorophyll, the green pigment of the plant that is responsible for photosynthesis.
Helps plants with rapid growth, increasing seed and fruit production and improving the quality of leaf and forage crops.
Nitrogen often comes from fertilizer application and from the air (legumes get their N from the atmosphere, water or rainfall contributes very little nitrogen)

Phosphorus (P)
Like nitrogen, phosphorus (P) is an essential part of the process of photosynthesis.
Involved in the formation of all oils, sugars, starches, etc.
Helps with the transformation of solar energy into chemical energy; proper plant maturation; withstanding stress.
Effects rapid growth.
Encourages blooming and root growth.
Phosphorus often comes from fertilizer, bone meal, and superphosphate.

Potassium (K)
Potassium is absorbed by plants in larger amounts than any other mineral element except nitrogen and, in some cases, calcium.
Helps in the building of protein, photosynthesis, fruit quality and reduction of diseases.
Potassium is supplied to plants by soil minerals, organic materials, and fertilizer.

Calcium (Ca)
Calcium, an essential part of plant cell wall structure, provides for normal transport and retention of other elements as well as strength in the plant. It is also thought to counteract the effect of alkali salts and organic acids within a plant.
Sources of calcium are dolomitic lime, gypsum, and superphosphate.

Magnesium (Mg)
Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth.
Soil minerals, organic material, fertilizers, and dolomitic limestone are sources of magnesium for plants.

Sulfur (S)
Essential plant food for production of protein.
Promotes activity and development of enzymes and vitamins.
Helps in chlorophyll formation.
Improves root growth and seed production.
Helps with vigorous plant growth and resistance to cold.
Sulfur may be supplied to the soil from rainwater. It is also added in some fertilizers as an impurity, especially the lower grade fertilizers. The use of gypsum also increases soil sulfur levels.


Micronutrients
Boron (B)
Helps in the use of nutrients and regulates other nutrients.
Aids production of sugar and carbohydrates.
Essential for seed and fruit development.
Sources of boron are organic matter and borax

Copper (Cu)
Important for reproductive growth.
Aids in root metabolism and helps in the utilization of proteins.

Chloride (Cl)
Aids plant metabolism.
Chloride is found in the soil.

Iron (Fe)
Essential for formation of chlorophyll.
Sources of iron are the soil, iron sulfate, iron chelate.

Manganese (Mn)
Functions with enzyme systems involved in breakdown of carbohydrates, and nitrogen metabolism.
Soil is a source of manganese.

Molybdenum (Mo)
Helps in the use of nitrogen
Soil is a source of molybdenum.

Zinc (Zn)
Essential for the transformation of carbohydrates.
Regulates consumption of sugars.
Part of the enzyme systems which regulate plant growth.
Sources of zinc are soil, zinc oxide, zinc sulfate, zinc chelate.



Non-Mineral Nutrients
The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon ©.

These nutrients are found in the air and water.
In a process called photosynthesis, plants use energy from the sun to change carbon dioxide (CO2 - carbon and oxygen) and water (H2O- hydrogen and oxygen) into starches and sugars. These starches and sugars are the plant's food.

Photosynthesis means "making things with light".

Since plants get carbon, hydrogen, and oxygen from the air and water, there is little farmers and gardeners can do to control how much of these nutrients a plant can use.


Mineral Nutrients
The 13 mineral nutrients, which come from the soil, are dissolved in water and absorbed through a plant's roots. There are not always enough of these nutrients in the soil for a plant to grow healthy. This is why many farmers and gardeners use fertilizers to add the nutrients to the soil.
The mineral nutrients are divided into two groups:
macronutrients and micronutrients.

Macronutrients

Macronutrients can be broken into two more groups:
primary and secondary nutrients.
The primary nutrients are nitrogen (N), phosphorus (P), and potassium (K). These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival.

The secondary nutrients are calcium (Ca), magnesium (Mg), and sulfur (S). There are usually enough of these nutrients in the soil so fertilization is not always needed. Also, large amounts of Calcium and Magnesium are added when lime is applied to acidic soils. Sulfur is usually found in sufficient amounts from the slow decomposition of soil organic matter, an important reason for not throwing out grass clippings and leaves.

Micronutrients
Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities . These elements are sometimes called minor elements or trace elements, but use of the term micronutrient is encouraged by the American Society of Agronomy and the Soil Science Society of America. The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients (as well as macronutrients) to growing plants.


Soil
In general, most plants grow by absorbing nutrients from the soil. Their ability to do this depends on the nature of the soil. Depending on its location, a soil contains some combination of sand, silt, clay, and organic matter. The makeup of a soil (soil texture) and its acidity (pH) determine the extent to which nutrients are available to plants.
Soil Texture (the amount of sand, silt, clay, and organic matter in the soil)

Soil texture affects how well nutrients and water are retained in the soil. Clays and organic soils hold nutrients and water much better than sandy soils. As water drains from sandy soils, it often carries nutrients along with it. This condition is called leaching. When nutrients leach into the soil, they are not available for plants to use.
An ideal soil contains equivalent portions of sand, silt, clay, and organic matter. Soils across North Carolina vary in their texture and nutrient content, which makes some soils more productive than others. Sometimes, the nutrients that plants need occur naturally in the soil. Othertimes, they must be added to the soil as lime or fertilizer.


Soil pH (a measure of the acidity or alkalinity of the soil)


Soil pH is one of the most important soil properties that affects the availability of nutrients.

Macronutrients tend to be less available in soils with low pH.
Micronutrients tend to be less available in soils with high pH.
Lime can be added to the soil to make it less sour (acid) and also supplies calcium and magnesium for plants to use. Lime also raises the pH to the desired range of 6.0 to 6.5.
In this pH range, nutrients are more readily available to plants, and microbial populations in the soil increase. Microbes convert nitrogen and sulfur to forms that plants can use. Lime also enhances the physical properties of the soil that promote water and air movement.

It is a good idea to have your soil tested. If you do, you will get a report that explains how much lime and fertilizer your crop needs.
 
Stoutman, when cutting and pasting from other sources, please acknowledge your source and include a URL back to the site.

Just to round out your soil nutrient primer. Many fertilisers contain the macronutrients but not the micronutrients. Make sure whatever you are using supplies the micronutrients as well as the macronutrients.

Hops are very heavy feeders. You can just about hear them growing. So keep the fertilizer up to them.
 
Not sure about those brands, read the ingredients. It should list the trace elements/micronutrients. If it doesn't list the trace elements and micronutrients, pick another brand. I use Organic Life which has trace elements in it.

Soil chemistry is a complex subject. Stoutman's basic primer is just the tip of the iceberg.
 
Now here is something that I'm really interested in.
I'm going to try POR next season in the back yard.
From what I know you"ll need a cool root run.good mulch and a fert high in nitrogen to start.(forming leaves) and more Phosphorous & potassium when the flowers start to form.You will need to add support 4 up to 5Mt growth(depending on aspect) so be ready.POR is the only lupulus gown commercially in the southern states as far as I know.
Good luck . Cant wait till next summer.
Cheers. Glenn.

My hops are going great guns but have a few white blemishes on the leaves. Is this due to a lack of a specific nutrient. .
[post="101727"][/post]​

At a guess it could be mildew,Powdery or downy.

If its just a few leaves remove and burn em.If its not hurting the plants health don't worry about it.Using chemicals such as sulphur etc.. is the last thing you would want to do.
 
i'm a bit cautious of adding anything to anything i'm going to eat without reading the fine print when i can
it seems a fair dose of these slow release fertilisers have heavy metals like cadmium and mercury
no thanks
worm poo, sheep sh!t and the occasional seaweed "safe" nutrients are added to mine and even though they're in a dodgy pot they're still growing like they're running on all 8 cylinders
start with some healthy soil and not a cheap bag of dried out ex-mushroom mix
someone on this site quoted the gardening dude from Tassie on the ABC - he lived on eating bugs in a foreign prison. fascinating bloke - he's my soil guru.

the bottom leaves naturally go yellow due to being close to the soil and picking up nasties, trim or pick them all off down the bottom (before or after they go yellow is up to you) i like before

and that's your bloomin lot
 
Dont worry about heavy metals. They wont make it into your beer. Humulus lupulus (hops) is a dioecious climbing perennial (1st cousin to cannabis) and a weed.
Lots of sun. A cool root run. Well mulched with chook poo down deep when U plant your rhysomes. Give plenty of height for growth and stand back.A fert with more phosphorus & potassium when you see flowers forming would help.Seasol and its clones are not ferterlisers but more like a tonic.Just like a beer. It might make U feel better but it wont make U grow.
Hope this helps
Cheers Glenn.
 
Ok Chippy.I think I know more about horticulture than brewing.I used to be keen gardener B4 the brewing obsession took over.I forgot to mention also keep the water up to them in the heat of summer.Maybe a soaker hose & if you plan on growing diff. varieties make sure they dont twine into each other or it will be a nightmare at harvest time.
Cheers Glenn.
