seems as though dried molasses is simply sprayed onto poultry/animal waste, @~ 1:3 ratio.

Dried molasses is beet sugar molasses sprayed on grain residue - more often than not it's rye seed residue.

ppm calculator

the differences in ppm readings, relevant to the g/ml inputs, using the ph/angelfire ppm calculator:

gh flora nova bloom, @ 15ml (~1 tbsp) per gal @ constant of 1g/1ml:
Nitrogen N Total 158.5
Phosphorus P 138.2
Potassium K 230.3
Magnesium Mg 79.3
Sulfur S 79.3
Calcium Ca 158.5
Iron Fe 3.96301

gh flora nova bloom, @ 15ml/gal, @ 1.5g/1ml:
Nitrogen N Total 237.9
Phosphorus P 207.5
Potassium K 345.6
Magnesium Mg 119.0
Sulfur S 119.0
Calcium Ca 237.9
Iron Fe 5.94764

&

gh flora nova bloom, @ 10ml/gal, @ 1.5g/1l:
Nitrogen N Total 158.6
Phosphorus P 138.3
Potassium K 230.4
Magnesium Mg 79.3
Sulfur S 79.3
Calcium Ca 158.6
Iron Fe 3.96509

...this means that gh fnb @ 10 ml (2 teaspoons) @ 1.5g/l, has ~exact same nutrient profile as 15 ml/ (1 tablespoon) @ 1g/ml...

so, if using calculators, or math to determine elemental ppms, change g/l for each bottle, or simply use 1g/1l as a constant. either should get approximate #'s.

different bottles of gh nova have different weights... this effects ppm readings. discussion in link resolves this be simply making 1g/1ml constant in this calculator:

gh fnb, 15ml/gal:

Creating a Solution with a Specific PPM

1. Determine the mass of the solvent in kilograms. If the solvent is water, one liter equals one kilogram. If you plan to dissolve fertilizer into 5 liters of water, the mass of your solvent would be five kilograms.
2. Determine the mass of the solute in milligrams. If the solute is part of a compound, determine how much of the compound is the solute. For example, if you add ten grams of fertilizer that is 20% nitrogen, multiply 1 gram times 0.2 (twenty percent) and you get 0.2 g. To get from grams to milligrams, multiply by 1000 and you get 200 milligrams.
3. Divide the mass of the solute in milligrams by the mass of the solvent in kilograms. In this example divide 200 by 5 and you get 40 parts per million (PPM).

*Make sure you use kilograms for the solvent and milligrams for the solute otherwise your parts per million concentration will be off.

above data should clarify why had issues w/ #'s of calc being different from long-form mathemetical equations, earlier in thread.

Very interesting, informative thread *mistress*. dongle, blue-dot, yo' sam, great contributions guys.

The 'Horticultural Molasses' you found really surprised me *m*, I would never have thought a sugar byproduct would need a warning like this :- Not for human consumption or food processing. May cause eye and skin irritation; wash thoroughly with water.
Do you have any idea why this product should be so different?

Fertiirrigation
According to Cortez (2000), fertirrigation is a joint process of irrigation and fertilization that consists of using the irrigation water to carry and distribute the chemical or organic fertilizer over the crops. It can be applied by any irrigation system. The fertilizer can be solid or liquid and must be dissolved or diluted before its use. Within this context, the term ‘fertirrigation’ as far as vinasse is concerned, is not entirely correct because its refers to the irrigation method used, for there is not a practical control over the applied water quantity nor over the application frequency. The sole interesting aspect is the amount of potassium carried by the vinasse and transferred to the soil. According to Luz (2005), vinasse can entirely replace the fertilization that uses potassium and sulfur and partially replace fertilization with nitrogen, a fact that is economically interesting because fertilization with potassium is carried out through the use of potassium chloride (KCl), which is costly. The use of fertirrigation is recommended for low fertile soils that demand large amounts of vinasse per area unit or for those soils that present high water deficit when irrigation is, then, necessary.
According to Rosenfeld (2003), the sugar/alcohol sector is the one that best uses its generated effluents. This use does not come from a growing environmental awareness alone, but mainly because the generated effluents have a large amount of nutrients and they do not present heavy metals in their composition. In certain cases, vinasse may present small amounts of antibiotics and acids used for decontaminating and washing equipment, which do not interfere with the fertilizing potential of this residue. Today Brazil has 653,312 hectares of fertirrigated areas, which correspond to a total of 12.44% of the cultivated area.
According to Cortez (2000), vinasse is a residue that is rich in colloidal organic matter and mineral elements, which contribute to elevating the pH of the soils and can even alkalinize then. In addition it improves the physicochemical and biological properties of the soils increasing their micro-flora. That is the reason why vinasse provides much more nitrification of the soil, giving it a higher fertility index, and then the sugarcane crops will present higher productivity along their vegetative cycle. This way, nearly all plants use the fertirrigation process nowadays as a way to dispose of the vinasse.
The extraordinary rise in the vinasse generated makes the distilleries increase the total amount of fertirrigated areas, when this is the case. However, the growth in the fertirrigated areas may not follow the amount of vinasse because, according to Normative Deliberation 12 of COPAM – December 16th, 1986 – establishing the complementary norms regarding the storage of effluents of sugar mills and alcohol distilleries, the application of vinasse is prohibited:

• In flooded areas or areas that are subjected to floods;
• In areas not farther than 200 m from streams and rivers;
• In areas where the underground water table is less than 2 meters;
• In Permanent Preserved Areas (PPA);
• Respecting a distance of 1,000 meters from population centers and 200 meters from railways and roads.

In addition, this norm establishes that, according to the origin of the wine, the following indexes of vinasse application to the soil must be respected: 450 m³/ha for direct juice vinasse, 300 m³/ha for blended juice vinasse and 150 m³/ha molasses vinasse
seems as though vinasse ~same of nutrients as molasses. is also a waste product from alcohol production, among other things.

molasses ~ npk [(kg/l)/3.785=~ppm per gallon)]

Question for calculation of DRY ferts like Maxibloom and Grow.

How would I calculate an NPK if I wanted to get the P lower than the N?

MaxiBloom 5-15-14 NPK

MaxiGrow 10-5-14 NPK

My initial thought was to do 2/3 Grow and 1/3 Bloom

How do I calculate what this would end up being?
