I fertilize my vegetables with Fish Emulsion. I wonder if the results are the same.

Eating five tomatoes a day could help protect against sunburn and premature ageing, new research has revealed. Experts at Manchester and Newcastle Universities found the fruit improved the skin's ability to protect itself against ultra-violet light.
The researchers calculated that the protection offered by eating tomatoes was comparable to applying factor 1.3 sunscreen.
The team is now hoping to carry out more research to find out if eating tomatoes can protect against more severe forms of sun-damage such as skin cancer.
"You don't have to eat an excessive amount of tomatoes to experience the effect, if you are already eating a tomato-based diet with plenty of things like spaghetti and pizza toppings," said Professor Mark Birch-Machin, a dermatology scientist at Newcastle University.
"Eating tomatoes is going to have this benefit in the sun, but it is still important to use conventional methods of protecting yourself against the sun such as sunscreens, shade and clothing."
Researchers studied the skin of 20 people, half of whom were given five tablespoons (55g) of standard tomato paste, the equivalent of five or six cooked tomatoes, with 10g of olive oil. The other half of the sample received just olive oil.
The experiment was carried out over 12 weeks and the group was exposed to ultra-violet light at the beginning and the end of the trial.
The results, presented to the British Society for Investigative Dermatology in Oxford, found that those who had eaten the paste had 33 per cent more protection against sunburn, which can lead to skin cancer.
Ultra-violet light leads to excess production of harmful molecules called 'reactive oxygen species', which can damage skin structures eventually causing wrinkles and skin cancer.
But tomatoes contain a powerful antioxidant called lycopene, which can neutralise these harmful molecules. Lycopene is the bright red pigment found in a number of fruit and vegetables, but is at its most concentrated in tomatoes.
The tomatoes were cooked and made into a paste, because the heating process frees up lycopene.
Analysis of skin samples from both groups also showed that the tomato diet had boosted the skin's procollagen levels, a molecule which gives the skin its structure. Losing procollagen leads to the skin ageing and losing its elasticity.
It was also found that the increased levels of lycopene reduced damage to mitochondrial DNA in the skin. Damage to that particular genetic material is also linked to ageing skin.
This is actually good news. Especially for farmers in places where the supply of freshwater is limited and can be supplemented with seawater.
Heh. Good one.
Beachwood 4-5789 has a special place in my heart. One night we were perfoming at the enlisted men’s club at Fort Ord, for a bunch of young, very drunk draftees. They told us if a fight broke out, whatever we did, do not stop playing. Well, the fight finally broke out while we were doing Beachwood, and we played it over and over for at least twenty minutes.
Never sang it again after that! Thanks for reminding me.
I live 10 minutes from the ocean.

Nothing beats home-grown tomatoes. Nothing.
This idea is demented. If you do this several years in a row, your soil will eventually not grow anything and the water table will become polluted with one of the most expensive contaminants - - salt.
Something similar happens when you irrigate year after year with hard water. The minerals accumulate in the soil eventually poisoning it.
Organic pollution eventually breaks down over time. Salt will never be anything but salt.

Will beat your price for diluted seawater by 50%. Call Jenny at 867-5309...
I wonder if the mixture used to make water for salt water aquariums would do the same thing set at a 12% level?
I can do better than that. Skip the diluted sea water and watch your tomatoes grow while drinking a pint of Guinness Stout. Much higher in antioxidants.
We have enough of sea water to irrigate the desert.
